[PATCH v2 08/11] spi: pxa2xx: Remove superflous check for Intel Atom SoCs

From: Andy Shevchenko
Date: Thu May 30 2024 - 11:12:39 EST


pxa2xx_spi_fw_translate_cs() checks for the ACPI companion device
presence along with the SSP type. But the SSP type is uniquely
determines the case. Hence remove the superflous check.
