Subject: [PATCH] s390: chps[] array too short
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=871931c1eef1727d42ff3ecf993b1978cf1e209f;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[PATCH] s390: chps[] array too short

The chps[] array in struct channel_subsystem is one too short; therefore the
code doesn't realize the chpid ff is already known.  When several devices on
chpid ff become available, the message "new_channel_path: could not register
ff" is displayed for every device but the first one.
