This patch introduces the use of API function setup_timer
instead of driver specific function init_timer as it is
the preferred and standard way to set and setup the timer.
To be compatible with the changes, argument types of
referenced functions are changed. Also, definition of
function _init_timer is removed as it is no longer needed
after this change.
Here, these cases are handled using Coccinelle and
semantic patch used for this is as follows:
@@ expression x, y; identifier a, b;@@
- _init_timer (&x, y, a, b);
+ setup_timer (&x, a, (unsigned long)b);

eth_zero_addr() is a wrapper function for memset if 0 is going to

1) We can tighten up the code a little by returning directly and it
makes the code more future proof and easier to read.
2) "free" is a better name than "exit".
3) sizeof(priv_cmd) is shorter and more clear than sizeof(struct
android_wifi_priv_cmd).

The original code had two bugs:
1) It didn't check if the string was zero length so it could oops when
it tried to dereference the ZERO_SIZE_PTR.
2) It didn't enforce that the string was NUL terminated.
It was also messy as pants.

The kernel used to contain two functions for length-delimited,
case-insensitive string comparison, strnicmp with correct semantics and
a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp
was renamed to strncasecmp, and strnicmp made into a wrapper for the new
strncasecmp to avoid breaking existing users.
To allow the compat wrapper strnicmp to be removed at some point in the
future, and to avoid the extra indirection cost, do
s/strnicmp/strncasecmp/g.
