Subject: staging: sync: fix return value check in sync_fence_alloc()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=59691367be00806a3ab1c6a125ced6ed87e91356;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

staging: sync: fix return value check in sync_fence_alloc()

In case of error, the function anon_inode_getfile() returns
ERR_PTR() and never returns NULL. The NULL test in the return
value check should be replaced with IS_ERR().
