From 574ff46f10102f65c40d24729197033a80458238 Mon Sep 17 00:00:00 2001 From: Tom Rix Date: Wed, 9 Feb 2022 06:52:54 -0800 Subject: [PATCH] drm/amdkfd: fix freeing an unset pointer clang static analysis reports this problem kfd_chardev.c:2092:2: warning: 1st function call argument is an uninitialized value kvfree(bo_privs); ^~~~~~~~~~~~~~~~ When bo_buckets alloc fails, it jumps to an error handler that frees the yet to be allocated bo_privs. Because bo_buckets is the first error, return directly.
