HSI: omap_ssi_port: fix debugfs_simple_attr.cocci warnings

2019-02-14T11:36:21+00:00

Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE
for debugfs files.

Semantic patch information:
Rationale: DEFINE_SIMPLE_ATTRIBUTE + debugfs_create_file()
imposes some significant overhead as compared to
DEFINE_DEBUGFS_ATTRIBUTE + debugfs_create_file_unsafe().

headers: separate linux/mod_devicetable.h from linux/platform_device.h

2018-07-07T15:52:26+00:00

At over 4000 #includes,  is the 9th most
#included header file in the Linux kernel.  It does not need
, so drop that header and explicitly add
 to source files that need it.

   4146 #include 

After this patch, there are 225 files that use ,
for a reduction of around 3900 times that 
does not have to be read & parsed.

    225 #include 

This patch was build-tested on 20 different arch-es.

It also makes these drivers SubmitChecklist#1 compliant.

HSI: omap_ssi: Use devm_kcalloc() in ssi_add_controller()

2017-06-08T11:21:43+00:00

* A multiplication for the size determination of a memory allocation
  indicated that an array data structure should be processed.
  Thus use the corresponding function "devm_kcalloc".

  This issue was detected by using the Coccinelle software.

* Replace the specification of a data type by a pointer dereference
  to make the corresponding size determination a bit safer according to
  the Linux coding style convention.
