Subject: clk: qcom: Fix clk_rcg2_is_enabled() check
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ad40aceaec1b7ba8bd2716544db4bb55214177b7;p=karo-tx-linux.git

clk: qcom: Fix clk_rcg2_is_enabled() check

commit aa014149ba002155a084ec1e9328e95b70167cbb upstream.

If the bit is set the clock is off so we should be checking for
a clear bit, not a set bit. Invert the logic.

Fixes: bcd61c0f535a (clk: qcom: Add support for root clock generators (RCGs))
