[PATCH v2 2/2] clk: test: use __clk_mux_determine_rate() and remove FIXME

From: Yang Xiwen via B4 Relay
Date: Tue Mar 05 2024 - 11:25:46 EST


From: Yang Xiwen <forbidden405@xxxxxxxxxxx>

Recent clk core fix resolved the bug in the FIXME comment. Now replace
the .determine_rate field back to __clk_mux_determine_rate() and remove
the FIXME comment.

Fixes: aebddfe2dfaf ("clk: test: Add a determine_rate hook")
