Subject: Eliminate gcc 4 'used uninitialized' warnings in drivers/qe/uccf.c
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1aa934c81b77f2080d3ca4b226eab67b17a33961;p=u-boot.git

Eliminate gcc 4 'used uninitialized' warnings in drivers/qe/uccf.c

give initial values for reg_num, shift, p_cmxucr in ucc_set_clk_src
since they are passed by reference to ucc_get_cmxucr_reg and assigned.
