From: Geert Uytterhoeven Date: Thu, 19 Feb 2009 15:46:49 +0000 (+0100) Subject: parisc: rtc: Rename rtc-parisc to rtc-generic X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3afe6d04626f8de87b15150a30b78df492ab68ee;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git parisc: rtc: Rename rtc-parisc to rtc-generic The rtc-parisc driver is not PA-RISC specific at all, as it uses the existing (but deprecated) generic RTC infrastructure ([gs]et_rtc_time()). Rename the driver from rtc-parisc to rtc-generic.
