Subject: rtc: sunxi: constify the data_year_param structure
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6ddab92faa2d7d7b38cb2b228f7fdfd1eecba5e2;p=linux-beck.git

rtc: sunxi: constify the data_year_param structure

The data_year_param struct is never modified, so lets constify it.
This permit to remove cast since of_device_id is const also.
