[PATCH 13/14] reset: ast2600: check dev_read_addr_ptr() for NULL

[David Lechner]

Check the return value of dev_read_addr_ptr() for NULL instead of
IS_ERR_OR_NULL(). This function only ever returns NULL on failure.

Replace the now-unused <linux/err.h> include with <errno.h>, which
is what actually provides the error code this driver uses.
