From 3bbdc083262dc082e5c8e7b0646faf8f4ef894dd Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 19 Jul 2021 10:48:42 +0300 Subject: [PATCH] spi: pxa2xx: Reuse int_stop_and_reset() in couple of places Reuse int_stop_and_reset() in couple of places. While at it, change the order of the int_stop_and_reset() and pxa2xx_spi_off() to be in align with the similar flow in int_error_stop().
