OMAP: hwmod: Remove IS_ERR check with omap_clk_get_by_name return value
The previous clock API was returning a standard linux error code in case of failure. This is not the case anymore with the new omap_clk_get_by_name API. A NULL value means that the clock node does not exist. Replace all the IS_ERR check by a !clk check. Signed-off-by: Benoit Cousson <b-cousson@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
