Subject: [PATCH] clk: Always clamp the rounded rate
|
|
|
|
The current core while setting the min and max rate properly in the
|
|
clk_request structure will not make sure that the requested rate is
|
|
within these boundaries, leaving it to each and every driver to make
|
|
sure it is.
|
|
|
|
Add a clamp call to make sure it's always done.
