Hi, * Mark Brown <broonie@xxxxxxxxxx> [191031 13:24]: > The patch > > spi: add power control when set_cs > > has been applied to the spi tree at > > https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-5.5 This patch causes a regression for many SPI devices as they assume spi_setup() return 0 on success and not a positive value. I've sent a fix for this as: spi: Fix regression to return zero on success instead of positive value Regards, Tony
