From 3e34b5135b39c4d530494e08d56b12f5b1396aa6 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 28 May 2020 17:18:58 +0300 Subject: [PATCH] i2c: acpi: Drop double check for ACPI companion device acpi_dev_get_resources() does perform the NULL pointer check against ACPI companion device which is given as function parameter. Thus, there is no need to duplicate this check in the caller.
