Subject: [PATCH] Input: Let the FT5x06 driver build without debugfs


When testing to make certain my user namespace code works
in various configurations I tripped over the tf5x06.c not
building with debugfs disabled.

drivers/input/touchscreen/edt-ft5x06.c: In function ‘edt_ft5x06_ts_remove’:
drivers/input/touchscreen/edt-ft5x06.c:846:14: error: ‘struct edt_ft5x06_ts_data’ has no member named ‘raw_buffer’

Fix the build by placing an #ifdef around the problem kfree.

Sorry for that.

There already is a patch for this issue which I slightly prefer. You
can find it in the mail from Guenther Roeck:

Thanks,
Simon

If you guys could get that merged into 3.6 I would appreciate it.

Yes, that would be great. I don't recall seeing an e-mail from Dmitry accepting
it, though.

This still affects Linus' tree and causes a build breakage without debugfs
configured. Considering the driver went into 3.5-rc5, could you please
push this fix for 3.6 (and mark it for stable backport)?

I Just sent a pull request to Linus.

I am pretty sure it was merged in 3.6 merge window, not 3.5, so no need
to mark for stable.

Thanks.
