Subject: [PATCH 3/4] power: reset: syscon-reboot-mode: Fix module autoload
Date: Mon, 17 Oct 2016 15:36:14 -0300	[thread overview]
Message-ID: <1476729375-17526-4-git-send-email-javier@osg.samsung.com> (raw)
In-Reply-To: <1476729375-17526-1-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/reset/syscon-reboot-mode.ko | grep alias
$

After this patch:

$ modinfo drivers/power/reset/syscon-reboot-mode.ko | grep alias
alias:          of:N*T*Csyscon-reboot-modeC*
alias:          of:N*T*Csyscon-reboot-mode
