Since commit 54196ccbe0 (of: consolidate linker section OF match table
declarations) which went into 3.16-rc1 the following compiler warning is
generated:
In file included from drivers/clk/clk-efm32gg.c:12:0: include/linux/of.h:772:20:
warning: comparison of distinct pointer types lacks a cast [enabled by default]
.data = (fn == (fn_type)NULL) ? fn : fn }
^
include/linux/of.h:785:3: note: in expansion of macro '_OF_DECLARE'
_OF_DECLARE(table, name, compat, fn, of_init_fn_1)
^
include/linux/clk-provider.h:545:42: note: in expansion of macro 'OF_DECLARE_1'
#define CLK_OF_DECLARE(name, compat, fn) OF_DECLARE_1(clk, name, compat, fn)
^
drivers/clk/clk-efm32gg.c:81:1: note: in expansion of macro 'CLK_OF_DECLARE'
CLK_OF_DECLARE(efm32ggcmu, "efm32gg,cmu", efm32gg_cmu_init);
^
Fix it by making efm32gg_cmu_init return void.
