but there is dependency to following commits as well:
03c4749dd6c7 ("gpio / ACPI: Drop unnecessary ACPI GPIO to Linux GPIO translation")
a60eac3239f0 ("pinctrl: intel: Allow custom GPIO base for pad groups")
I'm not sure whether they can be considered as stable material, though.
Given that:
https://github.com/torvalds/linux/commit/f5a26acf0162477af6ee4c11b4fb9cffe5d3e257.patch
Which is in 4.15.4 and later is causing a black screen on some model
laptops because the wrong GPIO number is causing the backlight-enable
pin to get configured wrongly, I don't think we have much choice here,
unless you want to revert that commit from stable, we are going to
need this patch as well as its 2 dependencies to fix the regression
in the 4.15.x series.
Yes, I agree. Let's try to get this to stable with the dependencies.
That should result a working touchpad and prevent the backlight issue as
well.
I guess stable tags would then look like following, if I read
Documentation/process/stable-kernel-rules.rst correctly:
Cc: stable@xxxxxxxxxxxxxxx # 03c4749dd6c7 ("gpio / ACPI: Drop unnecessary ACPI GPIO to Linux GPIO translation")
Cc: stable@xxxxxxxxxxxxxxx # a60eac3239f0 ("pinctrl: intel: Allow custom GPIO base for pad groups")
Cc: stable@xxxxxxxxxxxxxxx # v4.15
Linus, do you want me to resend the patch with these tags or are you
going to do that yourself?
Actually, it turns out that 03c4749dd6c7 ("gpio / ACPI: Drop unnecessary
ACPI GPIO to Linux GPIO translation") needs another fix because
otherwise certain Chromebook keyboards stop working (again). See:
https://bugzilla.kernel.org/show_bug.cgi?id=199463
So I'm thinking it may be better not to include these in stable and
revert
https://github.com/torvalds/linux/commit/f5a26acf0162477af6ee4c11b4fb9cffe5d3e257.patch >
from stable trees.
FWIW, that is fine with me.
Regards,
Hans
