Subject: [PATCH] MIPS: lantiq: add clk_round_rate()
|
||
|
|
|
||
|
|
This adds a basic implementation of clk_round_rate()
|
||
|
|
The clk_round_rate() function is called by multiple drivers and
|
||
|
|
subsystems now and the lantiq clk driver is supposed to export this,
|
||
|
|
but doesn't do so, this causes linking problems like this one:
|
||
|
|
ERROR: "clk_round_rate" [drivers/media/v4l2-core/videodev.ko] undefined!

||
