Subject: ERR_PTR() dereference in net/rds/ib.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=94713bab649736177a1c33a39b7bb33cbd5af3a5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ERR_PTR() dereference in net/rds/ib.c

rdma_create_id() doesn't return NULL, only ERR_PTR().

Found by smatch (http://repo.or.cz/w/smatch.git).  Compile tested.

regards,
dan carpenter
