From 3f07657506df363709a37f99db04e9e0d0b1bce7 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 19 Nov 2021 19:37:17 +0200 Subject: spi: deduplicate spi_match_id() in __spi_register_driver() The same logic is used in spi_match_id() and in the __spi_register_driver(). By switching the former from taking struct spi_device * to const char * as the second parameter we may deduplicate the code.
