Rather than wait until the patches hit vanilla and get backported via the stable kernel, this patch patches the crypto4xx driver with the latest fixes from the upstream linux-crypto tree. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>

Subject: [PATCH 01/15] treewide: kzalloc() -> kcalloc()
|
|
|
|
The kzalloc() function has a 2-factor argument form, kcalloc(). This
|
|
patch replaces cases of:
|
|
|
|
kzalloc(a * b, gfp)
|
|
|
|
with:
|
|
kcalloc(a * b, gfp)
|
|
|
|
as well as handling cases of:
|
|
|
|
kzalloc(a * b * c, gfp)
|
|
|
|
with:
|
|
|
|
kzalloc(array3_size(a, b, c), gfp)
|
|
|
|
as it's slightly less ugly than:
|
|
|
|
kzalloc_array(array_size(a, b), c, gfp)
|
|
|
|
This does, however, attempt to ignore constant size factors like:
|
|
|
|
kzalloc(4 * 1024, gfp)
|
|
|
|
though any constants defined via macros get caught up in the conversion.
|
|
|
|
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
|
|
dropped, since they're redundant.
|
|
|
|
The Coccinelle script used for this was:
