wait_for_completion_interruptible_timeout()
There is a confusing pattern in the kernel to use a variable named 'timeout' to
store the result of wait_for_completion_interruptible_timeout() causing patterns like:
timeout = wait_for_completion_interruptible_timeout(...)
if (!timeout) return -ETIMEDOUT;
with all kinds of permutations. Use 'time_left' as a variable to make the code
self explaining.
Fix to the proper variable type 'long' while here.

GCC 13.2 warns:
drivers/net/wireless/intersil/p54/fwio.c:128:34: warning: '%s' directive output may be truncated writing up to 39 bytes into a region of size 32 [-Wformat-truncation=]
drivers/net/wireless/intersil/p54/fwio.c:128:33: note: directive argument in the range [0, 16777215]
drivers/net/wireless/intersil/p54/fwio.c:128:33: note: directive argument in the range [0, 255]
drivers/net/wireless/intersil/p54/fwio.c:127:17: note: 'snprintf' output between 7 and 52 bytes into a destination of size 32
The issue here is that wiphy->fw_version is 32 bytes and in theory the string
we try to place there can be 39 bytes. wiphy->fw_version is used for providing
the firmware version to user space via ethtool, so not really important.
fw_version in theory can be 24 bytes but in practise it's shorter, so even if
print only 19 bytes via ethtool there should not be any practical difference.
I did consider removing fw_var from the string altogether or making the maximum
length for fw_version 19 bytes, but chose this approach as it was the least
intrusive.
Compile tested only.

Use bitmap_zalloc()/bitmap_free() instead of hand-writing them.
It is less verbose and it improves the semantic.

It seems like a historic accident that these return unsigned char *,
and in many places that means casts are required, more often than not.
Make these functions (skb_put, __skb_put and pskb_put) return void *
and remove all the casts across the tree, adding a (u8 *) cast only
where the unsigned char pointer was used directly, all done with the
following spatch:
@@
expression SKB, LEN;
typedef u8;
identifier fn = { skb_put, __skb_put };
@@
- *(fn(SKB, LEN))
+ *(u8 *)fn(SKB, LEN)
@@
expression E, SKB, LEN;
identifier fn = { skb_put, __skb_put };
type T;
@@
- E = ((T *)(fn(SKB, LEN)))
+ E = fn(SKB, LEN)
which actually doesn't cover pskb_put since there are only three
users overall.
A handful of stragglers were converted manually, notably a macro in
drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many
instances in net/bluetooth/hci_sock.c. In the former file, I also
had to fix one whitespace problem spatch introduced.

gcc 7 complains:
drivers/net/wireless/intersil/p54/fwio.c: In function 'p54_scan':
drivers/net/wireless/intersil/p54/fwio.c:491:4: warning: 'memset' used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size]
Fix that by passing the correct size to memset.
