Merge branch 'ofdeviceiddata' of git://git.pengutronix.de/git/ukl/linux into next/fixes-non-critical
From "Uwe Kleine-König" <u.kleine-koenig@pengutronix.de>: this is the 2nd version of this series whose goal is to make struct of_device_id.data const. Conceptually a driver must not modify the data contained there so making it const is the right thing. v1 of this series was sent with Message-id: 1342182734-321-1-git-send-email-y. Changes since then are: - powerpc fixes - several new consts that were found by Arnd that are possible after patch 19. Arnd suggested to take this series via arm-soc late for 3.6 in one go because patch 19 depends on the former patches but is a precondition to the latter and it fixes a few warnings. So getting it in via the respective maintainer trees would need a much bigger coordination effort. That means I prefer getting Acks over you taking the patch. Vinod Koul already took dmaengine: at_hdmac: add a few const qualifiers that is in next-20120723 as 7fd63ccdad72 now. Vinod, I don't follow your pull requests, but assuming you didn't let it already pull for 3.6 I suggest you drop it from your queue and I just take your Ack. This series was build tested for arm (all defconfigs) and powerpc (all defconfigs and an allyesconfig) and grep didn't find more issues. As before it introduces a warning in drivers/regulator/twl-regulator.c. This driver does modify its .of_match_table when a device is bound which doesn't fits the concept of independant devices. Arnd noticed another new warning in drivers/scsi/qlogicpti.c that isn't that easy to resolve, because the pointer to (now) const data is passed as first argument to scsi_host_alloc. To fix that properly struct Scsi_Host.hostt needs to get a const, too. Alternatively I could introduce a cast removing the const, but I don't like that. * 'ofdeviceiddata' of git://git.pengutronix.de/git/ukl/linux: (25 commits) dma: tegra: make data used as *of_device_id.data const can: mpc5xxx_can: make data used as *of_device_id.data const macintosh/mediabay: make data used as *of_device_id.data const i2c/mpc: make data used as *of_device_id.data const mfd/da9052: make i2c_device_id array const powerpc/fsl_msi: drop unneeded cast to non-const pointer gpio/gpio-omap: make platformdata used as *of_device_id.data const of: add const to struct *of_device_id.data dma: tegra: make tegra_dma.chip_data a pointer to const data watchdog/mpc8xxx: add a const qualifier powerpc/celleb_pci: add a const qualifier powerpc/fsl_msi: add a const qualifier powerpc/83xx: add a const qualifier macintosh/mediabay: add a const qualifier mmc/omap_hsmmc: add a const qualifier i2c/mpc: add a const qualifier i2c/i2c-omap: add a const qualifier gpio/mpc8xxx: add a const qualifier gpio/gpio-omap.c: add a const qualifier misc/atmel_tc: make atmel_tc.tcb_config member point to const data Signed-off-by: Arnd Bergmann <arnd@arndb.de> [olof: repulled a v3 version of the branch that rebased to add some more acked-bys and added one more patch on top for tegra] Signed-off-by: Olof Johansson <olof@lixom.net>
