249e7ced72 coccinelle: misc: secs_to_jiffies: implement context and report modes 
As requested by Ricardo and Jakub, implement report and context modes for
the secs_to_jiffies Coccinelle script.  While here, add the option to look
for opportunities to use secs_to_jiffies() in headers.

15c200eaf5 coccinelle: misc: secs_to_jiffies: Patch expressions too 
Patch series "Converge on using secs_to_jiffies() part two", v3.

This is the second series that converts users of msecs_to_jiffies() that
either use the multiply pattern of either of:
- msecs_to_jiffies(N*1000) or
- msecs_to_jiffies(N*MSEC_PER_SEC)

where N is a constant or an expression, to avoid the multiplication.

The conversion is made with Coccinelle with the secs_to_jiffies() script
in scripts/coccinelle/misc.  Attention is paid to what the best change can
be rather than restricting to what the tool provides.


This patch (of 16):

Teach the script to suggest conversions for timeout patterns where the
arguments to msecs_to_jiffies() are expressions as well.

551dbd1ec7 coccinelle: misc: add secs_to_jiffies script 
This script finds and suggests conversions of timeout patterns that result
in seconds-denominated timeouts to use the new secs_to_jiffies() API in
include/linux/jiffies.h for better readability.
