Function contains a local pointer variable defined to a memory location within a structure. This memory location is later used by dereferencing the struct instead of using the local pointer. The code is cleaner if all references of the same memory location use the local variable. Utilize existing local pointer variable instead of dereferencing struct. Signed-off-by: Tobin C.

Function uses overly complex calls to memcpy(). Code may be simplified by the use of a local variable. Code sometimes uses explicit address of initial array element and sometimes does not. Uniformity aids readability. If array pointers are explicit it aids readability further. Simplify calls to memcpy(). Add local pointer variable, define it to the correct memory location. Use newly defined variable in calls to memcpy(). Be uniform in use of explicit address of first element of array (&foo[0]). Signed-off-by: Tobin C.

Function parameter is cast to a local pointer which is then dereferenced before it is checked to be non-NULL. Move pointer null check to be before the pointer is dereferenced. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Multi-way decision contains two anomalies. Firstly, a local variable is defined to be the inverse truth variable of a struct member. This local variable is used as the conditional to the multi-way decision. This is unnecessary, the same logic can be expressed using the struct member directly. Secondly, there are four branches in the multi-way decision, two of which can never be executed. This is dead code. Remove unnecessary local variable. Remove two branches of multi-way decision statement that can never be executed. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Function contains compound statement delineated by lone braces. This statement represents a discreet set of functionality and thus can be factored out into a separate function. Using a separate function instead of a compound statement increases readability, reduces code indentation, reduces function length, and generally looks more tidy. Factor compound statement out to separate function. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Tobin C. Harding authored
Function has duplicate code clean up sequences; identical function call followed by return. This would be better expressed with the use of a goto statement, as is typical in-tree. One call site places the clean up code within the 'else' branch of an multi-way decision. This can be more clearly expressed by inverting the initial decision conditional and jumping directly to the cleanup code. Subsequent code indentation can then be reduced, aiding readability. Fix function return code execution path. Move clean up code to end of function with a label. Replace duplicate clean up code within function with a jump to label. Invert conditional, jump to label if new conditional evaluates to true, reduce indentation in subsequent code. Signed-off-by: Tobin C.

Function contains a list of four checks, for no apparent reason two of them are OR'ed together. Having two OR'ed together and the other two not implies some connection between the two that are combined. It is easier to read this code if the four unrelated checks are done as separate statements. Move dissimilar expressions out of logical continuation and into separate statement. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Function has return type 'int'. Function has internal linkage. Function returns 0 on all execution paths. Function is called only once in the driver and the return value is not checked. Removal of this return value does not change the program logic. The 'int' return type is not adding any information thus it is better to remove it. Change return type of function with internal linkage from 'int' to 'void'. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Tobin C. Harding authored
A number of functions have blocks of code guarded by an if statement. if (foo) { /* block of code */ } This can, on occasion, more succinctly be expressed as if (!foo) return /* block of code */ This change will mean a number of whitespace issues need to be addressed/fixed. The diff can be a little hard to read when there are multiple lines that are very similar (for example error return code). Splitting the indentation reduction and the whitespace fixes into two separate patches was not found to aid reading the diff. Therefor we fix the whitespace issues at the same time. We need to be very sure to not make any changes to the program logic, this is ensured by only doing what is stated - invert the conditional, fix whitespace. Invert if statement conditionals. Return if new conditional evaluates to true. Reduce level of indentation in subsequent code. Fix white space issues. Signed-off-by: Tobin C.

Function uses identifier 'retval' to hold the error return value. The rest of the driver uses 'ret' for this purpose. Being uniform in the choice of identifiers generally adds to the cleanliness of the code, also it is arguably easier to follow the code if one name is used for one task. Rename identifier 'retval' to 'ret'. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Length undergoes type conversion when passed (indirectly) as an argument for parameter of type 'unsigned int'. If length is negative this is a bug (the value after conversion is large).

Functions accept a parameter of type 'void *', this is then cast to a struct ks_wlan_private pointer. All call sites have a struct ks_wlan_private pointer and cast it to 'void *'. We can remove the unnecessary casting by changing the parameter type to match the usage. Functions changed all have internal linkage. Replace parameter of type 'void *' with 'struct ks_wlan_private *'. Remove unnecessary casting to and from 'void *'. Signed-off-by: Tobin C.
