If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 06fb398c032bd2317c2f2fdffd455c3e052265ca Author: Sergey Shtylyov <s.shtylyov@xxxxxx> Date: Sat Jun 17 23:36:19 2023 +0300 mmc: sdhci-spear: fix deferred probing [ Upstream commit 8d0caeedcd05a721f3cc2537b0ea212ec4027307 ] The driver overrides the error codes and IRQ0 returned by platform_get_irq() to -EINVAL, so if it returns -EPROBE_DEFER, the driver will fail the probe permanently instead of the deferred probing. Switch to propagating the error codes upstream. Since commit ce753ad1549c ("platform: finally disallow IRQ0 in platform_get_irq() and its ilk") IRQ0 is no longer returned by those APIs, so we now can safely ignore it... Fixes: 682798a596a6 ("mmc: sdhci-spear: Handle return value of platform_get_irq") Cc: stable@xxxxxxxxxxxxxxx # v5.19+Again, this patch (and the others as well) needs checking whether applying it to the stable kernels older than 5.19.y is safe... as the older kernels still could return IRQ0 from platform_get_irq(), etc.
I'll drop it, thanks. -- Thanks, Sasha
