Subject: thermal: max77620: Fix module autoload
X-Git-Tag: v5.15~12317^2~1^3~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3f2883e5bf12e2920f451d1ae831e44583e00364;p=platform%2Fkernel%2Flinux-starfive.git

thermal: max77620: 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/thermal/max77620_thermal.ko | grep alias
$

After this patch:

$ modinfo drivers/thermal/max77620_thermal.ko | grep alias
alias:          platform:max77620-thermal
