Subject: MIPS: Alchemy: Remove direct access to prepare_count field of struct clk
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=24c71c83ed5994f07aabe137decbe3434791938c;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

MIPS: Alchemy: Remove direct access to prepare_count field of struct clk

Replacing it with a call to __clk_is_prepared(), which isn't entirely
equivalent but in practice shouldn't matter.
