[PATCH v2 0/2] locking/mutex: Mark devm_mutex_init() as __must_check

[Thomas Weißschuh]

Even if it's not critical, the avoidance of checking the error code
from devm_mutex_init() call today diminishes the point of using devm
variant of it. Tomorrow it may even leak something. Enforce all callers
checking the return value through the compiler.

The series should go through the locking tree.
