From: Roman Volkov <[email protected]>
GCC 5.3.0 still throws the following warnings for functions
wm8750_find_pll_bits() and wm8850_find_pll_bits():
warning: 'best_div2' may be used uninitialized in this function
warning: 'best_div1' may be used uninitialized in this function
warning: 'best_mul' may be used uninitialized in this function
These warnings are false positives, the variables are controlled
by checking the value of the variable 'best_err' which is -1 by
default. It is safe to initialize all these variables to zero.
Fixes: 090341b0a95d ("clk: vt8500: fix sign of possible PLL values")
