Subject: i2c-omap: don't compile in OMAP15xx I2C ISR for non-OMAP15xx builds
X-Git-Tag: v2.6.26-omap1~64
X-Git-Url: http://www.pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=1eabd1df766765883eeead08c801b5b119d5904b;p=linux-2.6-omap-h63xx.git

i2c-omap: don't compile in OMAP15xx I2C ISR for non-OMAP15xx builds

Skip compiling OMAP15xx I2C ISR for non-OMAP15xx builds.  Saves 400 bytes
of text for most OMAP builds.
