Subject: [PATCH] Staging: atomisp: fix alloc_cast.cocci warnings
Date: Thu,  7 Sep 2017 18:26:42 +0200	[thread overview]
Message-ID: <20170907162642.2195-1-branislav@radocaj.org> (raw)

Remove casting the values returned by memory allocation functions
like kmalloc, kzalloc, kmem_cache_alloc, kmem_cache_zalloc etc.

Semantic patch information:
This makes an effort to find cases of casting of values returned by
kmalloc, kzalloc, kcalloc, kmem_cache_alloc, kmem_cache_zalloc,
kmem_cache_alloc_node, kmalloc_node and kzalloc_node and removes
the casting as it is not required. The result in the patch case may
need some reformatting.

Generated by: scripts/coccinelle/api/alloc/alloc_cast.cocci
