spi/spi-fsl-spi: reference correct pdata in fsl_spi_cs_control

2012-06-01T07:15:51+00:00

commit 067aa4815a9bc12a569d8a06afef50ba5773afbf upstream.

Commit 178db7d3, "spi: Fix device unregistration when unregistering
the bus master", changed spi device initialization of dev.parent pointer
to be the master's device pointer instead of his parent.

This introduced a bug in spi-fsl-spi, since its usage of spi device
pointer was not updated accordingly. This was later fixed by commit
5039a86, "spi/mpc83xx: fix NULL pdata dereference bug", but it missed
another spot on fsl_spi_cs_control function where we also need to update
usage of spi device pointer. This change address that.

spi/mpc83xx: fix NULL pdata dereference bug

2012-06-01T07:15:40+00:00

commit 5039a86973cd35bdb2f64d28ee12f13fe2bb5a4c upstream.

Commit 178db7d3, "spi: Fix device unregistration when unregistering
the bus master", changed device initialization to be children of the
bus master, not children of the bus masters parent device. The pdata
pointer used in fsl_spi_chipselect must updated to reflect the changed
initialization.

spi-topcliff-pch: Fix issue for transmitting over 4KByte

2012-05-21T17:46:23+00:00

commit 7d05b3e868ee0f9231baf40cb77be3df5dd1f18c upstream.

Currently, when spi-topcliff-pch receives transmit request over 4KByte,
this driver can't process correctly. This driver needs to divide the data
into 4Kbyte unit.
This patch fixes the issue.

spi-topcliff-pch: fix -Wuninitialized warning

2012-04-22T22:39:17+00:00

commit de3bd7e6de25141c466773c2e0fa319b2fa93655 upstream.

Fix for:
drivers/spi/spi-topcliff-pch.c: In function ‘pch_spi_handler_sub’:
drivers/spi/spi-topcliff-pch.c:325:17: warning: ‘bpw_len’ may be
  used uninitialized in this function [-Wuninitialized]
drivers/spi/spi-topcliff-pch.c:325:42: warning: ‘rx_index’ may be
  used uninitialized in this function [-Wuninitialized]
drivers/spi/spi-topcliff-pch.c:325:42: warning: ‘tx_index’ may be
  used uninitialized in this function [-Wuninitialized]

Move usage of tx_index, rx_index and bpw_len into the same
block as where they are set to prevent uninitialized usage.

v2: instead of init variables with 0 move the whole block

[This patch title "warnings" makes you think "This patch is not
for bug fix".  However, this patch surely patch for bug fix.]
