This lacks a description detailing why this change is necessary. While
I can see the sense in preventing a subsequent write succeeding after a
failed page register write, we still continue blindly on accessing the
device after a read or write fails. For istance, how many calls to
reg_write() or reg_read() are checked for failure?

That said, the patch does not appear to create any detrimental effects,
so it gets a tested-by but *no* acked-by. Please give it a better
description justifying this change for an acked-by.

Tested-by: Russell King <rmk+kernel@xxxxxxxxxxxxxxxx>
