Subject: media: tc358746: Address compiler warnings Author: Sakari Ailus <[email protected]> Date: Tue May 30 12:16:39 2023 +0200 Address these compiler warnings by initialising the m_best and p_best values to 0 and 1 respectively (as latter is used as a divisor): drivers/media/i2c/tc358746.c: In function 'tc358746_find_pll_settings': >> drivers/media/i2c/tc358746.c:817:13: warning: 'p_best' is used uninitialized [-Wuninitialized] 817 | u16 p_best, p; | ^~~~~~ >> drivers/media/i2c/tc358746.c:816:13: warning: 'm_best' is used uninitialized [-Wuninitialized] 816 | u16 m_best, mul; | ^~~~~~ The warnings may well be a false positive but it is difficult for a compiler to find out whether that truly is the case.
