Subject: proc: more debugging for "already registered" case
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=665020c35e89a9e0643e21561e4f8f967f4f2c4b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

proc: more debugging for "already registered" case

Print parent directory name as well.

The aim is to catch non-creation of parent directory when proc_mkdir will
return NULL and all subsequent registrations go directly in /proc instead
of intended directory.
