Subject: [PATCH 2/2] rtc: efi: add efi_procfs in efi_rtc_ops
Date: Sat, 7 Nov 2015 12:00:22 +0800 [thread overview]
Message-ID: <92f29256c04397cde0a3572982702dca359392b6.1446868545.git.geliangtang@163.com> (raw)
In-Reply-To: <9d57abe4fe1acdbc4a63496142ea4b78f152e621.1446868545.git.geliangtang@163.com>
In-Reply-To: <9d57abe4fe1acdbc4a63496142ea4b78f152e621.1446868545.git.geliangtang@163.com>
Add efi_procfs in efi_rtc_ops to show rtc-efi info in /proc/driver/rtc.
Most of the code comes from efi_rtc_proc_show() in efirtc.
