From: Jingoo Han Date: Tue, 20 Aug 2013 02:31:00 +0000 (+0100) Subject: staging: iio: replace strict_strto*() with kstrto*() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e5e26dd5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git staging: iio: replace strict_strto*() with kstrto*() The usage of strict_strto*() is not preferred, because strict_strto*() is obsolete. Thus, kstrto*() should be used. Previously, there were only strict_strtol(), strict_strtoul(), strict_strtoull(), and strict_strtoll(). Thus, when converting to the variables, only long, unsigned long, unsigned long long, and long long can be used. However, kstrto*() provides various functions handling all types of variables. Therefore, the types of variables can be changed properly.
