treewide: devm_kzalloc() -> devm_kcalloc()
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:
devm_kzalloc(handle, a * b, gfp)
with:
devm_kcalloc(handle, a * b, gfp)
as well as handling cases of:
devm_kzalloc(handle, a * b * c, gfp)
with:
devm_kzalloc(handle, array3_size(a, b, c), gfp)
as it's slightly less ugly than:
devm_kcalloc(handle, array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
devm_kzalloc(handle, 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.
Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".
The Coccinelle script used for this was:
