Hi Josh,
I've a patch for the Toshiba ACPI kernel driver fixing backlight issues
on various models, it fixes these 2 bugs:
https://bugzilla.redhat.com/show_bug.cgi?id=1206036
https://bugzilla.redhat.com/show_bug.cgi?id=1215989
Which are a regression starting with 3.19, since we got 2 bugs in a
short time this likely affects more users.
The fix for this got merged recently:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/dr...
I think it would be good to apply this to the Fedora 4.0 / 3.19
kernels, I've attached a version for those (resolves a 1 line conflict
in the #includes). I say I think because although it looks like this
patch will fix issues on various models, it may also introduce issues
on other models which is why I've not added a Cc: stable for upstream.
Still overall I think we should apply this.
Regards,
Hans
