Subject: [PATCH] clk: socfpga: remove set but not used variable 'rc'
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/clk/socfpga/clk-pll.c:83:6: warning: variable ‘rc’ set but
not used [-Wunused-but-set-variable]
The returned value of of_clk_add_provider() is never used, and so
can be removed.
Fixes: 97259e99bdc9 ("clk: socfpga: split clk code")
