[ Upstream commit 89e28da82836530f1ac7a3a32fecc31f22d79b3e ] When building with -Wsometimes-uninitialized, Clang warns: drivers/soc/mediatek/mtk-pmic-wrap.c:1358:6: error: variable 'rdata' is used uninitialized whenever '||' condition is true [-Werror,-Wsometimes-uninitialized] If pwrap_write returns non-zero, pwrap_read will not be called to initialize rdata, meaning that we will use some random uninitialized stack value in our print statement. Zero initialize rdata in case this happens.
