Subject: [PATCH 0337/1085] media: bcm2835-unicam: Set ret on error path in
|
|
unicam_async_complete()
|
|
|
|
Clang warns:
|
|
|
|
drivers/media/platform/bcm2835/bcm2835-unicam.c:3109:6: warning: variable 'ret' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]
|
|
if (!source_pads) {
|
|
^~~~~~~~~~~~
|
|
drivers/media/platform/bcm2835/bcm2835-unicam.c:3152:9: note: uninitialized use occurs here
|
|
return ret;
|
|
^~~
|
|
drivers/media/platform/bcm2835/bcm2835-unicam.c:3109:2: note: remove the 'if' if its condition is always false
|
|
if (!source_pads) {
|
|
^~~~~~~~~~~~~~~~~~~
|
|
drivers/media/platform/bcm2835/bcm2835-unicam.c:3091:9: note: initialize the variable 'ret' to silence this warning
|
|
int ret;
|
|
^
|
|
= 0
|
|
1 warning generated.
|
|
|
|
When the if condition is true, ret will be used uninitialized, which
|
|
could result in undesirable behavior. Set ret to -ENODEV on the error
|
|
path, which is a standard error code for the ->complete() callback.
