clk: qcom: gdsc: Bump parent usage count when GDSC is found enabled
When a GDSC is found to be enabled at boot the pm_runtime state will be unbalanced as the GDSC is later turned off. Fix this by increasing the usage counter on the power-domain, in line with how we handled the regulator state. Fixes: 1b771839de05 ("clk: qcom: gdsc: enable optional power domain support") Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Acked-by: Stephen Boyd <sboyd@kernel.org> Link: https://lore.kernel.org/r/20220713212818.130277-1-bjorn.andersson@linaro.org
