Subject: Fix the i2c frequency and default address in rsdproto board
X-Git-Tag: v1.3.0-rc4~3
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=fd329e6f05bbdfe6bd71b0e09f0c76d3b0a025a5;p=u-boot

Fix the i2c frequency and default address in rsdproto board

rsdproto board support has wrong I2C frequency and wrong return value
handling.
