[PATCH 3/4] clk: renesas: mstp: Clarify cpg_mstp_{at,de}tach_dev() domain parameter

Geert Uytterhoeven
2016-03-09T19:18:33Z

Make it clear that the "domain" parameter of the cpg_mstp_attach_dev()
and cpg_mstp_detach_dev() functions is not used.

The cpg_mstp_attach_dev() and cpg_mstp_detach_dev() callbacks are not
only used by the CPG/MSTP Clock Domain driver, but also by the R-Mobile
SYSC PM Domain driver.
