From 055d624facda577d3168951a1d6e2519e4fc30f7 Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Fri, 27 Jul 2018 10:48:28 +0800 Subject: isdn: hisax: config: Replace GFP_ATOMIC with GFP_KERNEL hisax_cs_new() and hisax_cs_setup() are never called in atomic context. They call kmalloc() and kzalloc() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself.
