From d04e0151d316edbdb4f0397a9b92a1936e4a1421 Mon Sep 17 00:00:00 2001 From: Osama Abdelkader Date: Sun, 10 May 2026 18:29:39 +0200 Subject: [PATCH] mmc: davinci: fix mmc_add_host order in probe mmc_add_host() makes the host visible to the MMC core. Register the interrupt handlers and advertise MMC_CAP_SDIO_IRQ before that, so the core cannot start using the host before IRQ handling is set up.
