Subject: linux-next: build warning after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (arm64 allmodconfig
clang-12) produced this warning:

kernel/locking/test-ww_mutex.c:138:7: error: variable 'ret' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]

Introduced by commit

  12235da8c80a ("kernel/locking: Add context to ww_mutex_trylock()")

-- 
Cheers,
Stephen Rothwell
