Subject: [PATCH 2/2] power: supply: axp288_fuel_gauge: Fix module autoload
Date: Mon, 17 Oct 2016 16:13:36 -0300	[thread overview]
Message-ID: <1476731616-23995-3-git-send-email-javier@osg.samsung.com> (raw)
In-Reply-To: <1476731616-23995-1-git-send-email-javier@osg.samsung.com>

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
