From 673831da643c31756622963585fc9d6dbb5d3a37 Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Fri, 27 Jul 2018 11:32:36 -0700 Subject: [PATCH] Input: keyspan_remote - replace GFP_ATOMIC with GFP_KERNEL in keyspan_probe() keyspan_probe() is never called in atomic context. It calls usb_alloc_coherent() 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.
