Subject: [PATCH 03/94] clk: ti: dra7: return error code in failure case

From: Julia Lawall <Julia.Lawall@...6.fr>

Add a returned error code in the MAX_APLL_WAIT_TRIES case.  Remove the
updating of the return variable r to 0 if MAX_APLL_WAIT_TRIES is not yet
reached, because r is already 0 at this point.
