Subject: [ARM] omap: remove clk_deny_idle and clk_allow_idle
X-Git-Tag: firefly_0821_release~15211^2~20^2~76
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ae8fce5c3baf84e319269e67823cf337ed9d359a;p=firefly-linux-kernel-4.4.55.git

[ARM] omap: remove clk_deny_idle and clk_allow_idle

Nothing makes any use of these functions, so there's little point in
providing them.
