Subject: [PATCH 01/10] cosa: Add missing kfree in error path of cosa_write
Git-commit: 52755b66ddcef2e897778fac5656df18817b59ab
Patch-mainline: v5.10-rc4
References: git-fixes
If memory allocation for 'kbuf' succeed, cosa_write() doesn't have a
corresponding kfree() in exception handling. Thus add kfree() for this
function implementation.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
