crypto: bfin_crc - Simplify use of devm_ioremap_resource

2016-07-05T15:05:24+00:00

Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to
devm_ioremap_resource.

The Coccinelle semantic patch that makes this change is as follows:

// 
@@
expression pdev,res,n,e,e1;
expression ret != 0;
identifier l;
@@

- res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  ... when != res
- if (res == NULL) { ... \(goto l;\|return ret;\) }
  ... when != res
+ res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  e = devm_ioremap_resource(e1, res);
//

crypto: bfin_crc - replace sg_count by sg_nents

2015-09-21T15:05:53+00:00

The sg_count function in bfin_crc.c is the same function as sg_nents.
Remove the duplicate code and use sg_nents() instead.

crypto: replace scatterwalk_sg_next with sg_next

2015-01-26T00:34:22+00:00

Modify crypto drivers to use the generic SG helper since
both of them are equivalent and the one from crypto is redundant.

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2014-12-15T00:10:09+00:00

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"

This is a specific implementation,  is the
multiplexer that has the arch-specific knowledge of which
of the implementations needs to be used, so include that.

cryptoo: bfin_crc - avoid get physical address of coherence memory by dma_map_single

2014-04-16T12:40:16+00:00

- The 4-byte sg_mid_buf is located in the middle of the coherence memory
sg_cpu. Don't call dma_map_single to get its physical address. Get the its
base physical address from the physical address of sg_cpu instead.
- Should set up the dma descriptor data after the 4-byte sg_mid_buf is
filled in completely from next sg buffer.
- memory copy from sg buffer should be done via virtual address.
- Remove unused reference to blackfin header
