Subject: power: supply: axp288_fuel_gauge: Fix module autoload
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=99e33fbdffc6d98ff8966b6a13a8fa53253a2974;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

power: supply: axp288_fuel_gauge: Fix module autoload

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/power/supply/axp288_fuel_gauge.ko | grep alias
$

After this patch:

$ modinfo drivers/power/supply/axp288_fuel_gauge.ko | grep alias
alias:          platform:axp288_fuel_gauge
