Subject: pinctrl: stmfx: update the result type of dm_i2c_reg_read
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=b10089233e27e6d6df0cb63cf6c25871b34c219a;p=u-boot.git

pinctrl: stmfx: update the result type of dm_i2c_reg_read

Use int as result of dm_i2c_reg_read to avoid warning with
W=1 (warning: comparison is always false due to limited range
of data type [-Wtype-limits])
