From 2453e60702e1a4d22720e3b6aac543e1a96fcd6b Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Mon, 30 Jul 2018 05:25:07 -0400 Subject: [PATCH] media: usb: em28xx: Replace GFP_ATOMIC with GFP_KERNEL in em28xx_init_usb_xfer() em28xx_init_usb_xfer() is never called in atomic context. It calls usb_submit_urb() 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.
