media: i2c: adv748x: Fix unsafe macros
commit0d962e061a
upstream. Enclose multiple macro parameters in parentheses in order to make such macros safer and fix the Clang warning below: drivers/media/i2c/adv748x/adv748x-afe.c:452:12: warning: operator '?:' has lower precedence than '|'; '|' will be evaluated first [-Wbitwise-conditional-parentheses] ret = sdp_clrset(state, ADV748X_SDP_FRP, ADV748X_SDP_FRP_MASK, enable ? ctrl->val - 1 : 0); Fixes:3e89586a64
