Subject: media: dvb-frontends/stv0367: remove redundant variable ADCClk_Hz
Author: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Date: Thu Oct 14 16:32:53 2021 +0100
GIT_AUTHOR_NAME=Colin King
GIT_AUTHOR_EMAIL=colin.king@xxxxxxxxxxxxx
Variable ADCClk_Hz is being initialised with a variable that is never read
and then re-assigned immediately afterwards. Clean up the code by removing
it and just returning the return value from the call to stv0367cab_get_mclk
Addresses-Coverity: ("Unused value")
