media: ccs: avoid printing an uninitialized variable
There is no intialization for the 'reg' variable, so printing it produces undefined behavior as well as a compile-time warning: drivers/media/i2c/ccs/ccs-core.c:314:49: error: variable 'reg' is uninitialized when used here [-Werror,-Wuninitialized] "0x%8.8x %s pixels: %d %s (pixelcode %u)\n", reg, Remove the variable and stop printing it. Fixes: fd9065812c7b ("media: smiapp: Obtain frame descriptor from CCS limits") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
