From 600ae40df788d282523b1b86624b83f7a11a97cb Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Thu, 20 May 2010 10:31:46 +0200 Subject: [ARM] pxa/palmtc: storage class should be before const qualifier The C99 specification states in section 6.11.5: The placement of a storage-class specifier other than at the beginning of the declaration specifiers in a declaration is an obsolescent feature.

After the v4l2 migration, the mt9m111 camera board information was not passed to the i2c layer anymore, but stored for future use of v4l2 (through soc_camera). Because mioa701_i2c_devices[] was tagged as "__initdata", and because after the v4l2 migration, the new structure "iclink" references it, the mt9m111 driver is not probed anymore, as part of "iclink" is not valid (discarded after kernel init). Although there is not compilation error, nor runtime oops, this patch restores a working camera on the mioa701 board.
