[PATCH] clk: mediatek: mt6735-mfgcfg: Publish the OF module alias

[PATCH] clk: mediatek: mt6735-mfgcfg: Publish the OF module alias

[hpp.iscas]

The MT6735 mfgcfg driver is built as an independent module when its
tristate option is m. Its platform-driver match table is not published
for OF modalias matching.

Publish the existing table while retaining the clock and reset setup.

clk: mediatek: mt6735-mfgcfg: Publish the OF module alias

This commit fixes module auto-loading for the MT6735 mfgcfg driver by
publishing its OF match table. The driver was built as a module but
lacked the module alias, preventing auto-loading.

[Severity: High]
This is a pre-existing issue, but does this fix need to be applied to
other drivers introduced in commit 0bd9b1211f74 as well?

Looking at drivers/clk/mediatek/clk-mt6735-imgsys.c, the clk_mt6735_imgsys
driver is also a tristate module with an OF match table, but it appears to be
missing the MODULE_DEVICE_TABLE declaration:

static const struct of_device_id of_match_mt6735_imgsys[] = {
	{ .compatible = "mediatek,mt6735-imgsys", .data = &imgsys_clks },
	{ /* sentinel */ }
};

static struct platform_driver clk_mt6735_imgsys = {
	.probe = mtk_clk_simple_probe,
	.remove = mtk_clk_simple_remove,
	.driver = {
		.name = "clk-mt6735-imgsys",
		.of_match_table = of_match_mt6735_imgsys,
	},
};

Without the table being exported, udev fails to auto-load the imgsys driver
on boot, which causes dependent imaging subsystems to fail to probe. Could we
include the missing MODULE_DEVICE_TABLE for clk-mt6735-imgsys in this patch
or a follow-up?
