The DPIO driver registers with the fsl-mc bus to handle bus-related events for DPIO objects. Key responsibility is mapping I/O regions, setting up interrupt handlers, and calling the DPIO service initialization during probe. Signed-off-by:

The DPIO service interface handles initialization of DPIO objects and exports APIs to be used by other DPAA2 object drivers to perform queuing and buffer management related operations. The service allows registration of callbacks when frames or notifications are received. Signed-off-by:

Code may be refactored to take advantage of previous patches which reduced the level of indentation. Function parameter line breaks can be adjusted in line with kernel coding standards. Refactor layout of function call parameters. Make whitespace changes only. Signed-off-by:

Checkpatch emits WARNING: Too many leading tabs - consider code refactoring. One level of indentation may be removed by inverting an if statement conditional (and returning if new conditional evaluates to true). Code contains switch statement that also contains multiple layers of indentation. Indentation may be reduced by breaking out of the case statement in multiple places instead of guarding code with if/else statements. Invert conditional. Return original error code if new conditional evaluates to true. Break out of case blocks instead of using if/else. Do not modify program logic. Signed-off-by:

Checkpatch emits WARNING: single byte memset is suspicious. Swapped 2nd/3rd argument? Call site in question is correct but is an unusual use of memset() to zero a single byte. The same can be achieved by assigning 0 directly to the memory location. Dereference pointer and assign 0 to that memory location. Use '\0' to make explicit that it is a char pointer. Signed-off-by:

Return value from kmalloc() does not require a cast. Remove unnecessary cast. Signed-off-by:

Checkpatch emits WARNING: else is not generally useful after a break or return. Two warnings of this type are emitted, both are the result of a else statement after a return statement. The 'else' can safely be removed. Remove unnecessary else statement. Signed-off-by:

Checkpatch emits WARNING: Comparisons should place the constant on the right side of the test. Move constant to right hand side of test, modify operator to ensure logic is maintained. Signed-off-by:

Checkpatch emits CHECK: multiple assignments should be avoided. Move multiple assignment onto separate lines. Fix comment to use more natural English. Signed-off-by:

Driver mixes spelling michael and michel in symbol names and comments. Michael here references the IEEE 802.11i Message Integrity Code. It is incorrect to spell it michel and confusing having two spellings for the same thing. Change michel -> micheal in both symbol names and comments. Signed-off-by:

I believe there is a missing break in the switch statement for case V4L2_CID_FOCUS_STATUS as the current fall-through looks suspect to me. Detected by CoverityScan, CID#1416580 ("Missing break in switch") Signed-off-by:Colin Ian King <colin.king@canonical.com> Signed-off-by:

Colin Ian King authored
There is no need to perform a null check on frame as there is an earlier null check check and return hence making the null check redundant. Remove it. Detected by CoverityScan, CID#1416563 ("Logically Dead Code") Signed-off-by: -

md_type is an enum. On my tests, GCC treats it as unsigned but according to the C standard it's an implementation dependant thing so we should check for negatives. Fixes: a49d2536 ("staging/atomisp: Add support for the Intel IPU v2") Signed-off-by:

The function atomisp_set_stop_timeout on being called, simply returns back. The function hasn't been mentioned in the TODO and doesn't have FIXME code around. Hence, atomisp_set_stop_timeout and its calls have been removed. This was done using Coccinelle. @@ identifier f; @@ void f(...) { -return; } Signed-off-by: -

This patch replaces NULL values returned by vc_vchi_audio_init(...) with error pointer values: - Return ERR_PTR(-EINVAL) when too many instances of audio service are initialised - Return ERR_PTR(-ENOMEM) when kzalloc fails - RETURN ERR_PTR(-EPERM) when vchi connections fail to open Similarly, a NULL check where vc_vchi_audio_init(...) is called is replaced by IS_ERR(..)

Function return type is 'int'. Returned variable is of type 'uint'. uint can be implicitly converted to int. Most significant bit is not set so there is no risk in implicit conversion. Remove unnecessary type cast. Signed-off-by:

Checkpatch emits CHECK: Blank lines aren't necessary before a close brace '}'. Previous attempts were made to make uniform the error handling in dgnc but improvements are still possible. Undo whitespace changes that should not have been made :(. Make return statement placement uniform throughout dgnc. Fix checkpatch CHECK. Make whitespace changes only. Signed-off-by:

In various functions a return code variable is defined at the top of function, for example; rc = -ENODEV; and then the variable is returned. This makes it harder to read since it separates the error code from the return site. Return the error code directly instead of using a variable. Signed-off-by:

Convert macro GAT_CONFIG to static inline function as static inline functions are preferred over macros. This change is possible since the arguments at all call sites have the same type. The uses were updated with Coccinelle: @r1@ expression dev,reg,chan,src; @@ -GAT_CONFIG(chan, src) +pci224_gat_config(chan, src) Also, the comment describing the macro has been removed.
