2018-06-12treewide: kmalloc() -> kmalloc_array()Kees Cook2-3/+3
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;

2018-03-01drm/omap: cleanup color space conversionTomi Valkeinen1-15/+44
The setup code for color space conversion is a bit messy. This patch cleans it up. For some reason the TRM uses values in YCrCb order, which is also used in the current driver, whereas everywhere else it's YCbCr (which also matches YUV order). This patch changes the tables to use the common order to avoid confusion. The tables are split into separate lines, and comments added for clarity. WB color conversion registers are similar but different than non-WB, but the same function was used to write both. It worked fine because the coef table was adjusted accordingly, but that was rather confusing. This patch adds a separate function to write the WB values so that the coef table can be written in an understandable way. Recalculation also showed that 'bcb' value in yuv-to-rgb conversion had been rounded wrongly, and it should be 516 instead of 517.

Also change omap_drv.c to call omap_fbdev_free() always, and omap_fbdev_free() does the check if fbdev was initialized. While at it, rename omap_fbdev_free() to omap_fbdev_fini() to better match the "init" counterpart. Signed-off-by: Tomi Valkeinen <[email protected]> Reviewed-by: Laurent Pinchart <[email protected]>
2018-03-01drm/omap: fix omap_fbdev_free() when omap_fbdev_create() wasn't calledTomi Valkeinen1-1/+2
If we have no crtcs/connectors, fbdev init goes fine, but omap_fbdev_create() is never called. This means that omap_fbdev->bo is NULL and omap_fbdev_free() crashes. Add a check to omap_fbdev_free() to handle the NULL case. Signed-off-by: Tomi Valkeinen <[email protected]> Reviewed-by: Laurent Pinchart <[email protected]>

2018-03-01drm: omapdrm: dss: Store DSS device pointer in the omapdrm private dataLaurent Pinchart5-12/+19
The dss_device is the top-level component in the omapdss driver. Give the omapdrm driver access to the dss_device pointer in order to obtain pointers to all other components from it. This requires a new global variable in the omapdss driver that will be removed when merging the omapdrm and omapdss drivers, but will already allow removal of several other global variables. As this partly duplicates the omapdss_is_initialized() API, reimplement it as an inline function wrapping omapdss_get_dss().

2018-03-01drm: omapdrm: dss: Pass omap_drm_private pointer to dss_mgr_opsLaurent Pinchart5-40/+64
The dss_mgr_ops operations implemented by the omapdrm side have to look up the omap_crtc objects from global variables as they are only passed a channel number. In order to remove global variables in the omapdrm driver pass the omap_drm_private pointer to the dss_mgr_ops. This requires storing a pointer to the omap_drm_private in a global variable on the DSS side as a temporary measure until the omapdrm and omapdss drivers get merged.
