mainline inclusion from mainline-v5.12-rc1-dontuse commit 205238f4ed3e14aed07a7b0121b94e404e65e78c category: feature bugzilla: 173966 CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Currently, a random stack value is being returned because variable _ret_ is not properly initialized. This variable is actually not used anymore and it should be removed.
Fix this by removing all instances of variable ret and return 0.
