This acks, no need for an ' here.

You'd have been better off sayinh:

Add support for the S3C64XX touchscreen to the s3c2410_ts driver, ensuring
it compiles and supports the extra features such as the interrupt generation.

hmm, does this correct a compile error?

It does, this has been mentioned in a previous version of this patch.
Last time I checked, this file wasn't available for S3C64xx targets.
Also, see below.

The s3c2410_gpio_cfgpin() and S3C2410_* aren't defined for S3C64xx builds.
