Subject: mfd: Replace strict_strtoul() with kstrtoul() in ab* and att*
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8420a24138e4ad7a8351bef136139ecb27cb15c5;p=linux-beck.git

mfd: Replace strict_strtoul() with kstrtoul() in ab* and att*

The usage of strict_strtoul() is not preferred, because
strict_strtoul() is obsolete. Thus, kstrtoul() should be
used.
