No, its most likely a problem with the updated patch from yesterday.
Could you please use the "-3" option with "git am" to apply this
patch? This works for me:

$ git am -3 ~/Downloads/U-Boot-5-6-v2-i2c-designware_i2c-Add-DM-support\(1\).patch
Applying: i2c: designware_i2c: Add DM support
Using index info to reconstruct a base tree...
M drivers/i2c/designware_i2c.c
Falling back to patching base and 3-way merge...
Auto-merging drivers/i2c/designware_i2c.c

Thanks,
Stefan
