Subject: Fix: nommu I2C adapter relocation error
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=83d271b5ffc19e98098861dd21e940cf53545a43;p=project%2Fbcm63xx%2Fu-boot.git

Fix: nommu I2C adapter relocation error

NoMMU systems have a access violation problem with i2c_reloc_fixup.
Blame for it is a double relocation of the adapter itself. The
i2c_adap_p is already relocated, if i2c_reloc_fixup is called.
This patch removes the relocation of i2c_adap_p from i2c_reloc_fixup
to fix this.
