Subject: [PATCH] Input: ads7846: Fix warning about output format

This patch fixes a compiler warning about wrong output format.

drivers/input/touchscreen/ads7846.c: In function 'ads7846_probe':
drivers/input/touchscreen/ads7846.c:1167: warning: format '%ld' expects
type 'long int', but argument 4 has type 'int'

Introduced by commit 067fb2f648543894ce775082c5636f4c32b99e4f ("Input:
ads7846 - return error on regulator_get() failure").

The ERR_PTR returns a long so the variable err needs to be long.

No, int works just as well. I have a patch that simply fixes format
specification.

Thanks.
