OpenWRT's developer guide prefers having actual patches so they an be sent upstream more easily. However, in this case, Adding proper fields also allows for `git am` to properly function. Some of these patches are quite old, and lack much traceable history. This commit tries to rectify that, by digging in the history to find where and how it was first added. It is by no means perfect and also shows some patches that should have been long gone. Signed-off-by: Olliver Schinagl <oliver@schinagl.nl>

Subject: gpio: realtek-otto: fix GPIO line IRQ offset
|
|
|
|
The irqchip uses one domain for all GPIO lines, so th line offset should be
|
|
determined w.r.t. the first line of the first port, not the first line of the
|
|
triggered port.
|
|
|
|
Fixes: 0d82fb1127fb ("gpio: Add Realtek Otto GPIO support")
