[PATCH] media: lmedm04: Use GFP_KERNEL for URB allocation/submission.

From: Malcolm Priestley
Date: Sat Oct 03 2020 - 05:32:49 EST



lme2510_int_read is not atomically called so use GFP_KERNEL for
usb_alloc_urb and usb_submit_urb which is the first in the chain
of interrupt submissions.

This patch is applied on top of
[likely] media: lmedm04: Fix misuse of comma

I have tested both patches with hardware and all is well.
