[PATCH][V2] of: overlay: fix memory leak of ovcs on error exit path

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Currently if the call to of_resolve_phandles fails then then ovcs
is not kfree'd on the error exit path.  Rather than try and make
the clean up exit path more convoluted, fix this by just kfree'ing
ovcs at the point of error detection and exit via the same exit
path.

Detected by CoverityScan, CID#1462296 ("Resource Leak")

Fixes: bd80e2555c5c ("of: overlay: Fix cleanup order in of_overlay_apply()")
