Subject: kernel/time/clocksource.c: Use list_for_each_entry instead of list_for_each
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2e1975868ac9d41211fcaa6f2c5e44c4e7ff9e5b;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

kernel/time/clocksource.c: Use list_for_each_entry instead of list_for_each

kernel/time/clocksource.c: Convert list_for_each to
list_for_each_entry in clocksource_resume(),
sysfs_override_clocksource() and show_available_clocksources()
