treewide: kmalloc() -> kmalloc_array()

2018-06-12T23:19:22+00:00

The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(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 tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

pcmcia: do not break rsrc_nonstatic when handling anonymous cards

2015-06-16T05:29:39+00:00

Patch 1c6c9b1d9d25 caused a regression for rsrc_nonstatic: It relies on pccard_validate_cis() to determine whether an iomem resource can be used for PCMCIA cards. This override, however, lead invalid iomem resources to be accepted -- and lead to a fake CIS being used instead of the original CIS. To fix this issue, move the override for anonymous cards to the one place where it is needed -- when adding a PCMCIA device. Signed-off-by: Dominik Brodowski
