Subject: [ARM] pxa: don't register lpd270 cpld_irq sysdev if !lpd270
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=720046de27ec2a96d4497dbca8ee98657efa059c;p=linux-beck.git

[ARM] pxa: don't register lpd270 cpld_irq sysdev if !lpd270

Don't register the LPD270 cpld_irq system device when we're not running
on a LPD270 machine - "cpld_irq" is also registered (separately) by
Lubbock and Mainstone.
