drm/gma500: fix potential NULL pointer dereference dereference

2017-08-18T07:10:46+00:00

NULL check at line 528: if (!sender || !data_out || !len_out) {, implies
that pointer _sender_ might be NULL.

Move pointer _sender_ dereference after NULL check in order to avoid a
potential NULL pointer dereference.

This issue was detected with the help of Coccinelle.

drm/gma500: Use .dumb_map_offset and .dumb_destroy defaults

2017-08-16T18:13:11+00:00

This driver can use the drm_driver.dumb_destroy and
drm_driver.dumb_map_offset defaults, so no need to set them.

include/linux/i2c is not for client devices. Move the header file to a

drm: gma500: remove dead code and pointless local lut storage

2017-08-04T09:35:51+00:00

The redundant fb helpers .gamma_set and .gamma_get are no longer
used. Remove the dead code and hook up the crtc .gamma_set
to use the crtc gamma_store directly instead of duplicating that
info locally.

drm/gma500: remove an unneeded NULL check

2017-06-28T17:17:38+00:00

"connector" is the list iterator and it can't be NULL.  It causes a
static checker warning because we dereference the iterator to get the
next item in the list.  Let's remove this check.

drm/pci: Deprecate drm_pci_init/exit completely

2017-06-20T08:41:03+00:00

The magic switching between proper pci driver and shadow-attach isn't
useful anymore since there's no ums+kms drivers left. Let's split this
up properly, calling pci_register_driver for kms drivers and renaming
the shadow-attach init to drm_legacy_pci_init/exit.

drm: Remove drm_driver->set_busid hook

2017-06-20T08:40:49+00:00

The only special-case is pci devices, and we can easily handle this in
the core. Do so and drop a pile of boilerplate from drivers.
