[PATCH] eeprom_93cx6: Add comment for 1us delay after pulse
This will add a comment for the 1us delay which is taken after the pulse has been switched. The 1us delay is based on the specifications so that should be made clear. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
