Subject: display: Change get_lcd_power() to dpms_get_cached_state()
X-Git-Tag: accepted/tizen/unified/20230330.025600~17
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c2b118b73f29161309e2edd7005238c375b10962;p=platform%2Fcore%2Fsystem%2Fdeviced.git

display: Change get_lcd_power() to dpms_get_cached_state()

To move plugin functions without plugin dependency,
get_lcd_power() should be replaced by dpms_get_cached_state().
However, touchscreen module is dependent on display module build.
Thus, this get_lcd_power() will be changed after resolving build dependency.
