Subject: mfd: hi655x-pmic: Fix module autoload when registered via OF
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e45b6c80b8bc1572788ed3d38bc2605eda20cd2b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mfd: hi655x-pmic: Fix module autoload when registered via OF

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/mfd/hi655x-pmic.ko | grep alias

After this patch:

$ modinfo drivers/mfd/hi655x-pmic.ko | grep alias
alias:          of:N*T*Chisilicon,hi655x-pmicC*
alias:          of:N*T*Chisilicon,hi655x-pmic
