2.6.37-stable review patch. If anyone has any objections, please let us know.
------------------ From: Takashi Iwai <[email protected]> commit ba3820ade317ee36e496b9b40d2ec3987dd4aef0 upstream. [The upstream commit above is a combination of revert + one-liner fix. This patch contains only the latter that is needed for 2.6.37.x.] This patch fixes the backlight level calculation for combination mode used in some models like GM45. It's due to a wrong bit shift introduced by the commit a95735569312f2ab0c80425e2cd1e5cb0b4e1870 drm/i915: Refactor panel backlight controls Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=23472 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=34524 Bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=672946 Signed-off-by: Takashi Iwai <[email protected]> --- drivers/gpu/drm/i915/intel_panel.c | 1 - 1 file changed, 1 deletion(-) --- a/drivers/gpu/drm/i915/intel_panel.c +++ b/drivers/gpu/drm/i915/intel_panel.c @@ -176,7 +176,6 @@ u32 intel_panel_get_backlight(struct drm val &= ~1; pci_read_config_byte(dev->pdev, PCI_LBPC, &lbpc); val *= lbpc; - val >>= 1; } } _______________________________________________ stable mailing list [email protected] http://linux.kernel.org/mailman/listinfo/stable
