Subject: [PATCH] clocksource: add __ro_after_init to cyclecounter
Date: Sun, 12 Feb 2017 00:50:18 +0530 [thread overview]
Message-ID: <1486840818-22214-1-git-send-email-bhumirks@gmail.com> (raw)
The object cyclecounter of type cyclecounter is not getting modified
after getting initialized by arch_counter_register. Apart from
initialization in arch_counter_register it is also passed as an argument
to the function timecounter_init but this argument is of type const.
Therefore, add __ro_after_init to its declaration.
