You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >>From 378da4a65f3a0390837b38145bb5d8c2d20c2cf7 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 7 Aug 2017 23:59:44 -0500 Subject: [PATCH] spi/bcm63xx-hspi: fix error return code in bcm63xx_hsspi_probe() platform_get_irq() returns an error code, but the spi-bcm63xx-hsspi driver ignores it and always returns -ENXIO. This is not correct and, prevents -EPROBE_DEFER from being propagated properly. Notice that platform_get_irq() no longer returns 0 on error: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af Print and propagate the return value of platform_get_irq on failure. This issue was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R.
