media: vb2: be sure to unlock mutex on errors
commit c06ef2e9acef4cda1feee2ce055b8086e33d251a upstream.
As reported by smatch:
drivers/media/common/videobuf2/videobuf2-core.c: drivers/media/common/videobuf2/videobuf2-core.c:2159 vb2_mmap() warn: inconsistent returns 'mutex:&q->mmap_lock'.
Locked on: line 2148
Unlocked on: line 2100
line 2108
line 2113
line 2118
line 2156
line 2159
There is one error condition that doesn't unlock a mutex.
Fixes: cd26d1c4d1bc ("media: vb2: vb2_mmap: move lock up")
