5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx> [ Upstream commit 74f45de394d979cc7770271f92fafa53e1ed3119 ] IRQs should be ready to serve when we call mmc_add_host() via tmio_mmc_host_probe(). To achieve that, ensure that all irqs are masked before registering the handlers.
