Subject: ubifs: Change value of mutex_is_locked()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=05ea83b67ed7861c1693187dbf3a2613601c1b15;p=u-boot.git

ubifs: Change value of mutex_is_locked()

The mutex lock and unlock functions are stubbed out and mutex_is_locked
was 0.  This caused asserts to fail in ubifs code when checking that the
mutex was locked.  For example,

UBIFS assert failed in ubifs_change_lp at 540
UBIFS assert failed in ubifs_release_lprops at 278

Assume that the "mutex" is locked since that is the normal case when it
is checked in the ubifs code.
