Introduce quirks and module parameters. 3 quirks are added:
1. Fixes reporting brightness keys twice since it's already handled by
acpi-video.
2. Some models need a short delay when setting battery thresholds to
prevent a race condition when two processes read/write. (will be used later)
3. Matebook X (2017) handles micmute led through the "legacy" interface
which is not currently implemented. Use ACPI EC method to control
this led. (will be used later)
2 module parameters are added to enable this short delay and/or report
brightness keys through this driver.
module parameters are a pain to manage and handle over time. Is there
any way you can "automatically" figure this out, or use a sysfs file
instead?
The patch also adds dmi matches to set the quirks, so the module params
are there to override those and/or to easily test which are the right options
with new modules. The normal / expected use-case for everything to be set
automatically based on the DMI table.
With that said, the module-params should really always override the dmi values,
so I would like to suggest to make the module-params int-s instead of bool-s
and to do something like this:
static int battery_reset = -1;
static int report_brightness = -1;
quirks = &quirk_unknown;
dmi_check_system(huawei_quirks);
/* If set the module options override the vale from the DMI table */
if (battery_reset != -1)
quirks->battery_reset = battery_reset;
if (report_brightness != -1)
quirks->report_brightness = report_brightness;
