[PATCH v3 00/12] mmc: use sdhci_pltfm_init for private allocation and clean up

[Jisheng Zhang]

These patches are to complete the TODOs in Commit 0e748234293f ("mmc:
sdhci: Add size for caller in init+register"), I.E:

- todo: migrate clients to using allocation this way
- todo: remove priv variable once migration is complete

Since v2:
 - based on mmc next tree and remove all priv usage introduced in newly
   commits in this tree
 - don't break two lines if sdhci_pltfm_init() call could be put into
   one line. Thank Ludovic Desroches.

Since v1:
 - add new patch03 to factorise sdhci_msm_pdata outisde of sdhci_msm_host.
   This is to fix drivers/mmc/host/sdhci-msm.c:440:32: warning: 'msm_host'
   is used uninitialized in this function [-Wuninitialized]
 - Add Arnd's Ack for all patches except patch3 which is new in v2

[PATCH v3 02/12] mmc: sdhci-esdhc-imx: use sdhci_pltfm_init for private allocation

[Jisheng Zhang]

Commit 0e748234293f ("mmc: sdhci: Add size for caller in init+register")
allows users of sdhci_pltfm to allocate private space in calls to
sdhci_pltfm_init+sdhci_pltfm_register. This patch migrates the sdhci
esdhc-imx driver to this allocation.

[PATCH v3 03/12] mmc: sdhci-msm: factorise sdhci_msm_pdata outisde of sdhci_msm_host

[Jisheng Zhang]

There's no need to allocate one sdhci_msm_pdata for each sdhci_msm_host.
This patch removes the sdhci_msm_pdata member from sdhci_msm_host and
uses one static global sdhci_msm_pdata for all sdhci msm hosts. It also
marks sdhci_msm_ops as const.

[PATCH v3 03/12] mmc: sdhci-msm: factorise sdhci_msm_pdata outisde of sdhci_msm_host

[Jisheng Zhang]

There's no need to allocate one sdhci_msm_pdata for each sdhci_msm_host.
This patch removes the sdhci_msm_pdata member from sdhci_msm_host and
uses one static global sdhci_msm_pdata for all sdhci msm hosts. It also
marks sdhci_msm_ops as const.

[PATCH v3 05/12] mmc: sdhci-of-arasan: use sdhci_pltfm_init for private allocation

[Jisheng Zhang]

Commit 0e748234293f ("mmc: sdhci: Add size for caller in init+register")
allows users of sdhci_pltfm to allocate private space in calls to
sdhci_pltfm_init+sdhci_pltfm_register. This patch migrates the
sdhci-of-arasan driver to this allocation.

[PATCH v3 07/12] mmc: sdhci-of-esdhc: use sdhci_pltfm_init for private allocation

[Jisheng Zhang]

Commit 0e748234293f ("mmc: sdhci: Add size for caller in init+register")
allows users of sdhci_pltfm to allocate private space in calls to
sdhci_pltfm_init+sdhci_pltfm_register. This patch migrates the
sdhci-of-esdhc driver to this allocation.

[PATCH v3 09/12] mmc: sdhci-st: use sdhci_pltfm_init for private allocation

Commit 0e748234293f ("mmc: sdhci: Add size for caller in init+register")
allows users of sdhci_pltfm to allocate private space in calls to
sdhci_pltfm_init+sdhci_pltfm_register. This patch migrates sdhci-st

[PATCH v3 10/12] mmc: sdhci-tegra: use sdhci_pltfm_init for private allocation

[Jisheng Zhang]

Commit 0e748234293f ("mmc: sdhci: Add size for caller in init+register")
allows users of sdhci_pltfm to allocate private space in calls to
sdhci_pltfm_init+sdhci_pltfm_register. This patch migrates sdhci-tegra
to this allocation.
