Subject: [media] media: davinci_vpfe: fix missing unlock on error in vpfe_prepare_pipeline()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4f388a9210e2a2c1cd83a5580b74aa13876dbf14;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[media] media: davinci_vpfe: fix missing unlock on error in vpfe_prepare_pipeline()

Add the missing unlock before return from function
vpfe_prepare_pipeline() in the error handling case.

video->lock is lock/unlock in function vpfe_open(),
and no need to unlock it here, so remove unlock
video->lock.
