media: smiapp: fix timeout checking in smiapp_read_nvm

2018-08-03T05:47:49+00:00

[ Upstream commit 7a2148dfda8001c983f0effd9afd8a7fa58e99c4 ] The current code decrements the timeout counter i and the end of each loop i is incremented, so the check for timeout will always be false and hence the timeout mechanism is just a dead code path. Potentially, if the RD_READY bit is not set, we could end up in an infinite loop. Fix this so the timeout starts from 1000 and decrements to zero, if at the end of the loop i is zero we have a timeout condition.

MAINTAINERS & files: Canonize the e-mails I use at files

2018-05-04T10:21:06+00:00

From now on, I'll start using my @kernel.org as my development e-mail. As such, let's remove the entries that point to the old mchehab@s-opensource.com at MAINTAINERS file. For the files written with a copyright with mchehab@s-opensource, let's keep Samsung on their names, using mchehab+samsung@kernel.org, in order to keep pointing to my employer, with sponsors the work. For the files written before I join Samsung (on July, 4 2013), let's just use mchehab@kernel.org. For bug reports, we can simply point to just kernel.org, as this will reach my mchehab+samsung inbox anyway.

Pull media fixes from Mauro Carvalho Chehab: "A series of media updates/fixes for 4.17. There are two important core fix patches in this series: - A regression fix on Kernel 4.16 with causes it to not work with some input devices that depend on media core - A fix at compat32 bits with causes it to OOPS on overlay, and affects the Kernels where the CVE-2017-13166 was backported The remaining ones are other random fixes at the documentation and on drivers. The biggest part of this series is a set of 18 patches for the Intel atomisp driver. Currently, it produces hundreds of warnings/errors on sparse/smatch, causing me to sometimes ignore new warnings on other drivers that are not so broken. This driver is on really poor state, even for staging standards: it has several layers of abstraction on it, and it supports two different hardware. Selecting between them require to add a define (there isn't even a Kconfig option for such purpose). Just on this smatch cleanup, I could easily get rid of 8 "do-nothing" files. So, I'm seriously considering its removal from upstream, if I don't see any real work on addressing the problems there along this year" * tag 'media/v4.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (48 commits) media: v4l2-core: fix size of devnode_nums[] bitarray media: v4l2-compat-ioctl32: don't oops on overlay media: i2c: adv748x: afe: fix sparse warning media: extended-controls.rst: transmitter -> receiver media: staging: atomisp: stop duplicating input format types media: staging: atomisp: get rid of an unused var media: staging: atomisp: stop mixing enum types media: staging: atomisp: get rid of some static warnings media: staging: atomisp: use %p to print pointers media: staging: atomisp: remove an useless check media: staging: atomisp: avoid a warning if 32 bits build media: staging: atomisp: don't access a NULL var media: staging: atomisp: Get rid of *default.host.[ch] media: staging: atomisp: get rid of an unused function media: staging: atomisp: remove unused set_pd_base() media: staging: atomisp: fix endianess issues media: staging: atomisp: add a missing include media: staging: atomisp: get rid of stupid statements media: staging: atomisp: declare static vars as such media: staging: atomisp: ia_css_output.host: don't use var before check ...

media: ov5640: add missing output pixel format setting

2018-04-04T10:12:53+00:00

The output pixel format changed by set_fmt() pad operation is not correctly applied. It is intended to be restored by calling ov5640_set_framefmt() when the video stream is started. However, when the device is powered on by s_power subdev operation before the video stream is started, the current output mode setting is restored by ov5640_restore_mode() that also clears pending_mode_change flag in ov5640_set_mode(). So ov5640_set_framefmt() isn't called as intended and the output pixel format is not restored. This change adds the missing output pixel format setting in the ov5640_restore_mode() that is called when the device is powered on.

media: ov5645: add missing of_node_put() in error path

2018-04-04T10:12:53+00:00

The device node obtained with of_graph_get_next_endpoint() should be released by calling of_node_put(). But it was not released when v4l2_fwnode_endpoint_parse() failed. This change moves the of_node_put() call before the error check and fixes the issue.
