From 08fda410bae41cc8dde9697f9104da525be53153 Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Mon, 15 Sep 2025 20:37:24 +0200 Subject: [PATCH] spi: reduce device chip select limit again The spi chipselect limit SPI_CS_CNT_MAX was raised with commit 2f8c7c3715f2 ("spi: Raise limit on number of chip selects") from 4 to 16 to accommodate spi controllers with more than 4 chip selects, and then later to 24 with commit 96893cdd4760 ("spi: Raise limit on number of chip selects to 24"). Now that we removed SPI_CS_CNT_MAX limiting the chip selects of controllers, we can reduce the amount of chip selects per device again to 4, the original value.
