From: Gustavo A. R. Silva Date: Tue, 15 Jan 2019 05:22:02 +0000 (-0600) Subject: drm/amdgpu: Replace kzalloc with kcalloc X-Git-Tag: v5.1-rc1~117^2~20^2~42 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=fe96b99dc72b16e3c8406ab17fe9e73e0aef1bd9;p=users%2Fdwmw2%2Flinux.git drm/amdgpu: Replace kzalloc with kcalloc Replace kzalloc() function with its 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a, b, gfp) Also, improve the coding style and the use of sizeof during allocation by changing sizeof(struct dc_surface_update) and sizeof(struct dc_plane_state) to sizeof(*updates) and sizeof(*surfaces), correspondingly. This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R.
