staging: kpc2000: fix error return code in kp2000_pcie_probe()

2020-05-27T15:48:22+00:00

commit b17884ccf29e127b16bba6aea1438c851c9f5af1 upstream.

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function. Also
removed var 'rv' since we can use 'err' instead.

staging: kpc2000: prevent underflow in cpld_reconfigure()

2020-04-01T08:58:14+00:00

commit 72db61d7d17a475d3cc9de1a7c871d518fcd82f0 upstream.

This function should not allow negative values of "wr_val".  If
negatives are allowed then capping the upper bound at 7 is
meaningless.  Let's make it unsigned.

Merge tag 'staging-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

2020-01-29T18:15:11+00:00

Pull staging and IIO updates from Greg KH:
 "Here is the big staging/iio driver patches for 5.6-rc1

  Included in here are:

   - lots of new IIO drivers and updates for that subsystem

   - the usual huge quantity of minor cleanups for staging drivers

   - removal of the following staging drivers:
       - isdn/avm
       - isdn/gigaset
       - isdn/hysdn
       - octeon-usb
       - octeon ethernet

  Overall we deleted far more lines than we added, removing over 40k of
  old and obsolete driver code.

  All of these changes have been in linux-next for a while with no
  reported issues"

staging: kpc2000: rename variables with kpc namespace

2020-01-22T08:53:44+00:00

Some namings in kpc2000_i2c are too ambiguous that may causing
confusion to the readers.

Rename some variable, function and struct name to prefix with 'kpc_i2c'
to eliminate confusions.

Staging: kpc2000: Remove warning: "dubious: x | !y" detected by sparse

2020-01-22T08:44:43+00:00

Sparse complains about "dubious: x | !y".

This patch adds some macros to make it clear if a flag will be enabled or
not so Sparse stops complaining about dubious code construct.

remove ioremap_nocache and devm_ioremap_nocache

2020-01-06T08:45:59+00:00

ioremap has provided non-cached semantics by default since the Linux 2.6
days, so remove the additional ioremap_nocache interface.

staging: kpc2000: remove unnecessary assertions in kpc_dma_transfer

2020-01-03T10:04:57+00:00

In kpc_dma_transfer(), the assertion that priv is NULL and priv->ldev
is NULL, are never satisfied. The two callers of the function,
dereference the fields before the function is called. This patch
removes the two BUG_ON calls.
