Subject: mach-ux500: fix i2c0 device setup regression
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cf568c58eb192368f5e796df935704535b54f451;p=linux-beck.git

mach-ux500: fix i2c0 device setup regression

Adding two sets of I2C devices to the same bus doesn't quite work,
atleast not anymore. Stash one array and determine how much of it
shall be added instead.
