Subject: USB: failure in usblp's error path
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6c8df79f8c0f8d861ea25e6e104a29398d8398f4;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

USB: failure in usblp's error path

if urb submission fails due to a transient error here eg. ENOMEM
, the driver is dead. This fixes it.
