From 2f9a0c880d5c1e159f647950a2eed26618ad2ff1 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Wed, 18 Apr 2012 06:43:09 -0300 Subject: [PATCH 01/12] [media] V4L: soc-camera: protect hosts during probing from overzealous user-space If multiple clients are registered on a single camera host interface, the user-space hot-plug software can try to access the one, that probed first, before probing of the second one has completed. This can be handled by individual host drivers, but it is even better to hold back the user-space until all the probing on this host has completed. This fixes a race on ecovec with two clients registered on the CEU1 host, which otherwise triggers a BUG() in sh_mobile_ceu_remove_device().

The reason was that IRQs were being triggered before a driver initialisation was completed. This patch fixes this by moving the invocation to request_irq() and to request_region() to a later stage on the driver probe function.
