Clang warns:
kernel/locking/test-ww_mutex.c:138:7: error: variable 'ret' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
if (!ww_mutex_trylock(&mutex, &ctx)) {
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
kernel/locking/test-ww_mutex.c:172:9: note: uninitialized use occurs here
return ret;

kernel/locking/test-ww_mutex.c:138:3: note: remove the 'if' if its condition is always false
if (!ww_mutex_trylock(&mutex, &ctx)) {
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
kernel/locking/test-ww_mutex.c:125:9: note: initialize the variable 'ret' to silence this warning
int ret;

1 error generated.
Assign !ww_mutex_trylock(...) to ret so that it is always initialized.
