[ Upstream commit 35a1744423743247026668e2323d1b932583fc2a ]
As the previous commit implies, a system may have a different SPI bus number that is embedded in the device string. And, assuming the fixed bus number is rather fragile; it may be assigned differently depending on the configuration or on the boot environment. Once when a bus number change happens, the binding fails, resulting in the silence.
This patch tries to make the matching a bit more relaxed, allowing to bind with a different bus number (or without it). So the previous fix, the introduction of ALC245_FIXUP_CS35L41_SPI1_2 fixup became superfluous, and this is unified to ALC245_FIXUP_CS35L41_SPI_2.
