Subject: remoteproc: qcom: q6v5_pil: Fix module autoload
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3227c876fb9a50fd7169fe265f236acce9ac2d2f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

remoteproc: qcom: q6v5_pil: 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/remoteproc/qcom_q6v5_pil.ko | grep alias
$

After this patch:

$ modinfo drivers/remoteproc/qcom_q6v5_pil.ko | grep alias
alias:          of:N*T*Cqcom,q6v5-pilC*
alias:          of:N*T*Cqcom,q6v5-pil
