Subject: [PATCH 1/2] spi: spi-pci1xxxx: Drop MSI-X usage as unsupported by DMA engine
Date: Sat, 14 Jun 2025 17:13:10 +0900	[thread overview]
Message-ID: <20250614081312.763606-2-ewhk9887@gmail.com> (raw)
In-Reply-To: <20250614081312.763606-1-ewhk9887@gmail.com>

From: Thangaraj Samynathan <thangaraj.s@microchip.com>

Removes MSI-X from the interrupt request path, as the DMA engine used by
the SPI controller does not support MSI-X interrupts.
