[PATCH 01/32] clk: mediatek: mt2712: fix memory leak on module removal

clk_mt2712_apmixed_probe() in clk-mt2712-apmixedsys.c does not call
platform_set_drvdata(), but clk_mt2712_apmixed_remove() callback calls
platform_get_drvdata().
This results in platform_get_drvdata() returning NULL, which leads to
calling kfree(NULL) in mtk_free_clk_data(NULL).
This leaves clk_data unreleased, causing a memory leak.

Fix this by calling platform_set_drvdata() during probe.

Fixes: c6368ce86435 ("clk: mediatek: mt2712-apmixedsys: Add .remove() callback for module build")
