The function setup_timer combines the initialization of a timer with the initialization of the timer's function and data fields. So, this patch combines the multiline code for timer initialization using the function setup_timer. This issue is identified via coccinelle script. @@ expression E1, E2, E3; type T; @@ - init_timer(&E1); ... ( - E1.function = E2; ... - E1.data = (T)E3; + setup_timer(&E1, E2, (T)E3); | - E1.data = (T)E3; ... - E1.function = E2; + setup_timer(&E1, E2, (T)E3); | - E1.function = E2; + setup_timer(&E1, E2, 0); ) Signed-off-by:

Using functions of the form __constant_<foo> isn't preferred outside of include/uapi/ as using the function without __constant_ is identical when the argument is a constant. So, this patch replaces __constant_htons with htons. This is done using Coccinelle and semantic patch used for this is as follows: @@identifier x;@@ ( - __constant_htons(x) + htons(x) | - __constant_htonl(x) + htonl(x) | - __constant_ntohs(x) + htons(x) | - __constant_ntohl(x) + htonl(x) ) Signed-off-by:

Use timer API function del_timer_sync instead of driver specific function _cancel_timer as besides deactivating a timer, it also ensures that the timer is stopped on all CPUs before the driver exists. Also, variables timer_cancelled and bool are removed as they are no longer needed. @A@ expression x; identifier y; @@ - _cancel_timer (&x, &y); + del_timer_sync (&x); @@type T; identifier a.y;@@ - T y; ...when != y Signed-off-by:

Use timer API function del_timer_sync instead of driver specific function _cancel_timer_ex as besides deactivating a timer, it ensures that the timer is stopped on all CPUs before the driver exists. Also, definition of function _cancel_timer_ex is removed as it is no longer needed after this change. This is done using Coccinelle and semantic patch used for this is as follows: @@ expression x; @@ - _cancel_timer_ex (&x); + del_timer_sync (&x); Signed-off-by:

Handles the following issues: Removing extra parentheses around function arguments, Removing unnecessary pointer to pointer casts.

Parentheses removal were left to the script. However, there were some cases that were handled manually. In addition, handling pointer casts were done manually too because not all replacements generated by the script were suitable. When pointer casts on function arguments were in the form: <func>(...,(<type> *)&<expression>,...) the replacements were discarded due to compilation warnings. Signed-off-by: -
