2018-07-05drm/radeon: use pcie functions for link widthAlex Deucher
This is the last user of drm_pcie_get_speed_cap_mask. Use the pci version so we can drop drm_pcie_get_speed_cap_mask. Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook
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: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2017-03-29drm: Use pr_cont where appropriateJoe Perches
Using 'printk("\n")' is not preferred anymore and using printk to continue logging messages now produces multiple line logging output unless the continuations use KERN_CONT. Convert these uses to appropriately use pr_cont or a single printk where possible. Miscellanea: o Use a temporary const char * instead of multiple printks o Remove trailing space from logging by using a leading space instead Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
