[PATCH linux-next] clk/keystone: fix application of sizeof to pointer

[PATCH linux-next] clk/keystone: fix application of sizeof to pointer

[jing yangyang]

sizeof when applied to a pointer typed expression gives the size of
the pointer.

./drivers/clk/keystone/sci-clk.c:398:8-14: ERROR application of sizeof to pointer

This issue was detected with the help of Coccinelle.

I am trying to understand this.. bsearch uses base + size to do
iteration, provider is sci_clk_provider ->num_clocks is struct sci_clk
** same as clk. iteration is done on provider->clocks .. not on *clk,
am I missing something? or is it one of those testing patches?
