The caller could have a small buf passed (less then < blen).
Since, the length of count and blen is not checked, it can
write beyond the end of buf.

If the CLK_SET_RATE_PARENT flag for the mmss_mdss_byte_intf_div_clk
divider is set re-calculation of dividers in DSI byte clock path takes
place which causes both the byte clock and byte interface clock to be
set to the same value.

The SD card specification allows cards to error out a SWITCH command
where the requested function in a group is not supported. The spec
provides for a set of capabilities which indicate which functions are
supported.
In the case of the power limit, requesting an unsupported power level
via the SWITCH command fails, resulting in the power level remaining at
the power-on default of 0.72W, even though the host and card may support
higher powers levels.
This has been seen with SanDisk 8GB cards, which support the default
0.72W and 1.44W (200mA and 400mA) in combination with an iMX6 host,
supporting up to 2.88W (800mA). This currently causes us to try to set
a power limit function value of '3' (2.88W) which the card errors out
on, and thereby causes the power level to remain at 0.72W rather than
the desired 1.44W.
Arrange to limit the selected current limit by the capabilities reported
by the card to avoid the SWITCH command failing. Select the highest
current limit that the host and card combination support.
