linux-toradex.git/drivers/regulator, branch v2.6.32.50 Linux kernel for Apalis and Colibri modules regulator: Fix display of null constraints for regulators 2010-02-23T15:37:49+00:00 Mark Brown broonie@opensource.wolfsonmicro.com 2010-02-11T19:20:48+00:00 bb0d31fbf221f50a44ba5d59dfcf54bbf128ac2b commit 973e9a2795b3b41d8408a0bb6f87b783c5efc88a upstream. If the regulator constraints are empty and there is no voltage reported then nothing will be added to the text displayed for the constraints, leading to random stack data being printed. This is unlikely to happen for practical regulators since most will at least report a voltage but should still be fixed.

commit 973e9a2795b3b41d8408a0bb6f87b783c5efc88a upstream.

If the regulator constraints are empty and there is no voltage
reported then nothing will be added to the text displayed for the
constraints, leading to random stack data being printed. This is
unlikely to happen for practical regulators since most will at
least report a voltage but should still be fixed.

regulator: Specify REGULATOR_CHANGE_STATUS for WM835x LED constraints 2010-02-09T12:50:53+00:00 Mark Brown broonie@opensource.wolfsonmicro.com 2010-01-04T15:30:54+00:00 00362b9adebdca260ae03717665a16f6948a6a4a commit a2fad9bf26a1d44a8d31a5c4528108a2b9f468ab upstream. The WM8350 LED driver needs to be able to enable and disable the regulators it is using. Previously the core wasn't properly enforcing status change constraints so the driver was able to function but this has always been intended to be required.
