6f8e7a83de media: cxusb, dib0700: ignore XC2028_I2C_FLUSH
commit 9893b905e743ded332575ca04486bd586c0772f7 upstream.

The XC2028_I2C_FLUSH only needs to be implemented on a few
devices. Others can safely ignore it.

That prevents filling the dmesg with lots of messages like:

	dib0700: stk7700ph_xc3028_callback: unknown command 2, arg 0

0a418e5771 media: dib0700: fix invalid dvb_detach argument
commit eb0c19942288569e0ae492476534d5a485fb8ab4 upstream.

dvb_detach(arg) calls symbol_put_addr(arg), where arg should be a pointer
to a function. Right now a pointer to state->dib7000p_ops is passed to
dvb_detach(), which causes a BUG() in symbol_put_addr() as discovered by
syzkaller. Pass state->dib7000p_ops.set_wbd_ref instead.

commit 67b0503db9c29b04eadfeede6bebbfe5ddad94ef upstream.

The buffer allocation for the firmware data was changed in
commit 43fab9793c1f ("[media] dvb-usb: don't use stack for firmware load")
but the same applies for the reset value.

2f7496c48a dib0700: fix nec repeat handling
commit ba13e98f2cebd55a3744c5ffaa08f9dca73bf521 upstream.

When receiving a nec repeat, ensure the correct scancode is repeated
rather than a random value from the stack.  This removes the need for
the bogus uninitialized_var() and also fixes the warnings:

    drivers/media/usb/dvb-usb/dib0700_core.c: In function ‘dib0700_rc_urb_completion’:
    drivers/media/usb/dvb-usb/dib0700_core.c:679: warning: ‘protocol’ may be used uninitialized in this function

[sean addon: So after writing the patch and submitting it, I've bought the
             hardware on ebay. Without this patch you get random scancodes
             on nec repeats, which the patch indeed fixes.]

3139f43f8e [media] Technisat SkyStar USB HD,(DVB-S/S2) too much URBs for arm devices
Using 8 URBs results in a consecutive buffer allocation of too much
memory for some arm devices.
As we use isochronuous transfers the number of URBs can be reduced
without risking data-loss.

38dcdca387 [media] pctv452e: Replace memset with eth_zero_addr
Use eth_zero_addr to assign the zero address to the given address
array instead of memset when second argument is address of zero.
Note that the 6 in the third argument of memset appears to represent
an ethernet address size (ETH_ALEN).

The Coccinelle semantic patch that makes this change is as follows:

// <smpl>
@eth_zero_addr@
expression e;

-memset(e,0x00,6);

0df289a209 [media] dvb: Get rid of typedev usage for enums
The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.

So, let's do it.

This patch was generated by this shell script:

	for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

While here, make CodingStyle fixes on the affected lines.

0fae1997f0 [media] dib0700: avoid the risk of forgetting to add the adapter's size
For every frontend entry, we need to add the adapter's size. There
are already two patches fixing it. So, it doesn't seem trivial to
keep it there at the right place.

Also, currently, the indentation is wrong on all places.

So, it seems that keeping it right is not too trivial.

Better to use a macro that would do it for us, at least while
this is not converted to dvb-usb-v2.

Compile-tested only.

If the streaming_ctrl is called to enable TS before demod has locked
the TS will be empty. Copied the solution from the dvbsky driver for the

lock, call su3000_streaming_ctrl again.

add an option to choose which output shall be used.

As this patch changes the default behaviour, the IF interface is
specified in each driver currently using si2157 driver. This is to

a2ea556117 [media] stv090x: remove export symbol for stv090x_set_gpio()
Drivers that use dvb_attach can have just one exported symbol,
or they will cause compilation breakages depending on the
selected frontends.

As Jim reported:
drivers/built-in.o: In function `technisat_usb2_set_voltage':
technisat-usb2.c:(.text+0x3b4919): undefined reference to `stv090x_set_gpio'
make: *** [vmlinux] Error 1

That happens because, on his configuration, the configuration
is:

	CONFIG_DVB_USB=y
	CONFIG_DVB_STV090x=m

Luis proposed ar way to fix, but that would just force the
STV090x to be selected, even if one wants to use a device
with a different frontend.

Instead, let's do the right thing: move set_gpio to the
configuration structure and fill it during dvb_attach().

This way, the driver can still call it, and dvb_attach()
will load stv090x module only if the device really needs it.

For TT CT2-4400v2 a TS stream related parameter needs to be set, otherwise the stream becomes corrupted. The Windows driver for both CT2-4400 and CT2-4400v2 sets this as well. After this patch the driver works for both versions.

af9005_usb_module_init() return pointers != NULL although the IR
symbols are not available.

The prefered fix would be to convert the whole IR code to use the kernel IR
infrastructure (which wasn't available at the time this driver had been created).

Until anyone who still has this old hardware steps up an does the conversion,
fix it by not calling the symbol_request calls if the driver is compiled in
without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE).
Due to the IR related pointers beeing NULL by default, IR support will then be disabled.

The downside of this solution is, that it will no longer be possible to
compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in.

Please note that this patch has NOT been tested with all possible cases.
I don't have the hardware and could only verify that it fixes the reported
bug.

09628b2c21 [media] dib0700_devices: Use c99 initializers for structures.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@decl@
identifier i1,fld;
type T;
field list[n] fs;
@@

struct i1 {
 fs
 T fld;
 ...};

@bad@
identifier decl.i1,i2;
expression e;
initializer list[decl.n] is;
@@

struct i1 i2 = { is,
+ .fld = e
- e
 ,...};
// </smpl>

Not sure why, but some tables are still using the old way,
but at least several of them got fixed.
