From 40216842dca4fa485cb1aa5eb231149a4a57cc85 Mon Sep 17 00:00:00 2001 From: Nicolas Pitre Date: Fri, 5 Mar 2010 13:43:34 -0800 Subject: [PATCH] sdio: kick the interrupt thread upon a resume Some SDIO cards may suspend while keeping function interrupts active especially in the powered suspend case. Upon resume we need to kick the SDIO interrupt thread to check for pending interrupts and to restart card IRQ detection at the host controller level.
