Subject: msm: mdss: avoid removing wrong multirect on validate failures
|
||
|
|
|
||
|
|
During atomic commit - validate failures, the newly allocated
|
||
|
|
pipes and pipes taken from the destroy list are cleaned up.
|
||
|
|
Currently pipe ndx is checked which can lead to cleaning up
|
||
|
|
the already in use multirect instead of the rect allocated
|
||
|
|
in the current validate. Add checks to include checking based
|
||
|
|
on multirect to avoid such cases.
|
||
|
|
