Centralize CAP_SYS_XXX checks to avoid duplicate code and missing checks in
the drivers.

[PATCH] RTC: rtc-dev UIE emulation2006-06-25T17:01:13+00:00Atsushi Nemotoanemo@mba.ocn.ne.jp2006-06-25T12:48:17+00:00urn:sha1:655066c3835e7b51794c4d56f042eb78b5a79f53
Import genrtc's RTC UIE emulation (CONFIG_GEN_RTC_X) to rtc-dev driver with
slight adjustments/refinements. This makes UIE-less rtc drivers work
better with programs doing read/poll on /dev/rtc, such as hwclock. This
emulation should not harm rtc drivers with UIE support, since
rtc_dev_ioctl() calls underlaying rtc driver's ioctl() first.

[PATCH] rtc subsystem: use ENOIOCTLCMD and ENOTTY where appropriate2006-05-21T19:59:21+00:00Alessandro Zummoalessandro.zummo@towertech.it2006-05-20T22:00:29+00:00urn:sha1:b3969e5831adac133b286600e74214e1ae42ec05
Appropriately use -ENOIOCTLCMD and -ENOTTY when the ioctl is not
implemented by a driver.
(akpm: we're not allowed to return -ENOIOCTLCMD to userspace. This patch does
the right thing).

[PATCH] RTC: rtc-dev tweak for 64-bit kernel2006-05-02T01:17:46+00:00Atsushi Nemotoanemo@mba.ocn.ne.jp2006-05-01T19:16:16+00:00urn:sha1:3418ff76119da52f808eb496191d1fd380f53f3d
Make rtc-dev work well on 64-bit platforms with 32-bit userland. On those
platforms, users might try to read 32-bit integer value. This patch make
rtc-dev's read() work well for both "int" and "long" size. This tweak is came
from genrtc driver.

[PATCH] RTC subsystem: dev interface2006-03-27T16:44:51+00:00Alessandro Zummoa.zummo@towertech.it2006-03-27T09:16:41+00:00urn:sha1:e824290e5dcfaf2120da587b16d10dfdff8d5d3e
Add the dev interface to the RTC subsystem.
Each RTC will be available under /dev/rtcX . A symlink from /dev/rtc0 to
/dev/rtc cab be obtained with the following udev rule:
KERNEL=="rtc0", SYMLINK+="rtc"
