[media] b2c2: use IS_REACHABLE() instead of open-coding it

2017-02-03T09:12:59+00:00

The FE_SUPPORTED() macro is basically the same as IS_REACHABLE, except that it causes a warning with gcc-7: common/b2c2/flexcop-fe-tuner.c:30:1: error: this use of "defined" may not be portable [-Werror=expansion-to-defined] common/b2c2/flexcop-fe-tuner.c:30:1: error: this use of "defined" may not be portable [-Werror=expansion-to-defined] common/b2c2/flexcop-fe-tuner.c:30:1: error: this use of "defined" may not be portable [-Werror=expansion-to-defined] Using IS_REACHABLE() to define it avoids the warning.

[media] rc-main: assign driver type during allocation

2017-01-30T15:59:57+00:00

The driver type can be assigned immediately when an RC device requests to the framework to allocate the device. This is an 'enum rc_driver_type' data type and specifies whether the device is a raw receiver or scancode receiver. The type will be given as parameter to the rc_allocate_device device. Change accordingly all the drivers calling rc_allocate_device() so that the device type is specified during the rc device allocation. Whenever the device type is not specified, it will be set as RC_DRIVER_SCANCODE which was the default '0' value.

[media] rc: raw IR drivers cannot handle cec, unknown or other

unknown and other are for IR protocols for which we have no decoder, so the raw IR drivers have no chance of generating them. cec is not an IR protocol. Signed-off-by: Sean Young Cc: Jiri Kosina Cc: Benjamin Tissoires Cc: Bruno Prémont Signed-off-by: Mauro Carvalho Chehab

[media] media: Drop FSF's postal address from the source code files

2017-01-27T13:38:09+00:00

Drop the FSF's postal address from the source code files that typically contain mostly the license text. Of the 628 removed instances, 578 are outdated. The patch has been created with the following command without manual edits: git grep -l "675 Mass Ave\|59 Temple Place\|51 Franklin St" -- \ drivers/media/ include/media|while read i; do i=$i perl -e ' open(F,"< $ENV{i}"); $a=join("", ); $a =~ s/[ \t]*\*\n.*You should.*\n.*along with.*\n.*(\n.*USA.*$)?\n//m && $a =~ s/(^.*)Or, (point your browser to) /$1To obtain the license, $2\n$1/m; close(F); open(F, "> $ENV{i}"); print F $a; close(F);'; done Signed-off-by: Sakari Ailus

[media] v4l2-tpg: Init hv_enc field with a valid value

2016-11-29T14:12:13+00:00

Zero is not a valid value for hsv_enc. Set the field to a valid initial value. This is not a problem for vivid, because it sets the field to 180 via tpg_s_hsv_enc() on the control initialization, but it might be a source of errors for other drivers that use this code.

[media] saa7146: Fix for while releasing video buffers

Fix this bug: "[BUG] process stuck when closing saa7146 [dvb_ttpci]" Release queued DMA buffers when ending streaming, so that videobuf_waiton() doesn't block forever.

[media] dvb: make DVB frontend *_ops instances "const"

2016-11-18T17:00:22+00:00

These are immutable. Making them "const" allows the compiler to move them to the "rodata" section. Note that cxd2841er_t_c_ops cannot be made "const", because cxd2841er_attach() modifies it. Ouch!
