Subject: i2c: tegra: Avoid error message on deferred probe
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d680a50cb9c59669d4f695f732731ed298a31bec;p=linux.git

i2c: tegra: Avoid error message on deferred probe

If the driver defers probe because of a missing clock, avoid outputting
an error message. The clock will show up eventually.
