From 1f34b20404443717a7ec77b447d86578f0478550 Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Sat, 30 Apr 2016 09:12:46 +0200 Subject: NFC: st-nci: spi: Drop two useless checks in ACPI probe path When st_nci_spi_acpi_request_resources() gets called we already know that the entries in ->acpi_match_table have matched ACPI ID of the device. In addition spi_device pointer cannot be NULL in any case (otherwise SPI core would not call ->probe() for the driver in the first place). Drop the two useless checks from the driver.
