From: Jia-Ju Bai Date: Fri, 27 Jul 2018 18:35:17 +0000 (-0700) Subject: Input: aiptek - replace GFP_ATOMIC with GFP_KERNEL in aiptek_probe() X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=53fddb6618db53779d96f6a29a98e2a9c5d05877;p=openwrt%2Fstaging%2Fblogic.git Input: aiptek - replace GFP_ATOMIC with GFP_KERNEL in aiptek_probe() aiptek_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.
