Subject: mlx4_core: Avoid double free_icms
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1af92e2a211b0d46ef60ea9f30f989fd7b5725fa;p=linux-beck.git

mlx4_core: Avoid double free_icms

On the error path of mlx4_init_hca(), mlx4_close_hca() is called,
followed by mlx4_free_icms() and mlx4_UNMAP_FA().  But both those
functions are also called from mlx4_close_hca(), which leads to a
double free.
