Thomas Arbrahams's patchset have changed the device name in sdhci-s3c.c
(mmc: sdhci-s3c: Rework platform data and add device tree support)
But didn't change the regulator_consumer name.
So maybe didn't initialize the mmc/sd card for exynos4.
This patch is fixed that (based-on linux-samsung for-next branch)

In mmc, there are capabilities and use the host_caps.
That capability is expressed with bit[0:31].
But now..already filled the bit[0:31]...
so we need to denote with the other capability field.
(if we want to use the cache, powerclass, etc for eMMC..
this field is necessary)

Add functions to register various video devices like venc, osd,
vpbe and the v4l2 display driver for dm644x.
Change dm644x_init_video() to make room for display related
configuration. Register the vpfe or vpbe devices only if valid
display configuration is provided to make sure boards without
video support dont erroneously register video devices.

Amba core assumes the pclk to be named as apb_pclk. During device probe,
it tries to get that clock and enable that. When PM_RUNTIME is enabled,
dma clock is not explicitly enabled in pl330_probe, which causes device
probe to fail. Adding a clkdev entry for apb_pclk for mdma1 fixes the
problem.
This patch fixes following runtime error.
dma-pl330 dma-pl330.2: PERIPH_ID 0x0, PCELL_ID 0x0 !
dma-pl330: probe of dma-pl330.2 failed with error -22

Bump core version to v4.1.0-rc2-ml, and for versions from the

This patch fixes a bug in tcm_fc where fc_exch memory from fc_exch_mgr->ep_pool
is currently being leaked by ft_send_resp_status() usage. Following current
code in ft_queue_status() response path, using lport->tt.seq_send() needs to be
followed by a lport->tt.exch_done() in order to release fc_exch memory back into
libfc_em kmem_cache.
ft_send_resp_status() code is currently used in pre submit se_cmd ft_send_work()
error exceptions, TM request setup exceptions, and main TM response callback
path in ft_queue_tm_resp(). This bugfix addresses the leak in these cases.

This patch converts iscsi-target session code to use se_sess->sess_kref
counting for iscsi session shutdown. The following cases include:
*) last iscsit_close_connection() shutdown path to invoke close session
*) iscsit_logout_post_handler_closesession() for explict logout
*) iscsit_free_session() caller for explict shutdown
It also moves iscsit_stop_session() call from lio_tpg_close_session()
into lio_tpg_shutdown_session() TFO callbacks to invoke an explict
shutdown, and also changes iscsi_check_for_session_reinstatement()
login code to use se_sess->sess_kref.

This patch converts core_tpg_del_initiator_node_acl() shutdown from configfs
context to use se_node_acl->acl_kref and ->acl_free_comp in order to wait for
outstanding fabric callbacks to complete via transport_deregister_session()
callbacks before waking ->acl_free_comp from the last ->acl_kref put.
It also changes core_tpg_del_initiator_node_acl() to setup a local sess_list
with target_get_session() + acl->acl_stop = 1 for active sessions that will
be shutdown, and changes transport_deregister_session_configfs() to check
for ->acl_stop usage.
