media: rc: compile rc-cec.c into rc-core

2021-03-17T16:03:40Z

commit f09f9f93afad770a04b35235a0aa465fcc8d6e3d upstream. The rc-cec keymap is unusual in that it can't be built as a module, instead it is registered directly in rc-main.c if CONFIG_MEDIA_CEC_RC is set. This is because it can be called from drm_dp_cec_set_edid() via cec_register_adapter() in an asynchronous context, and it is not allowed to use request_module() to load rc-cec.ko in that case. Trying to do so results in a 'WARN_ON_ONCE(wait && current_is_async())'. Since this keymap is only used if CONFIG_MEDIA_CEC_RC is set, we just compile this keymap into the rc-core module and never as a separate module.

media: v4l2-device.h: Explicitly compare grp{id,mask} to zero in v4l2_device macros

2020-02-24T07:36:36Z

[ Upstream commit afb34781620274236bd9fc9246e22f6963ef5262 ] When building with Clang + -Wtautological-constant-compare, several of the ivtv and cx18 drivers warn along the lines of: drivers/media/pci/cx18/cx18-driver.c:1005:21: warning: converting the result of '<<' to a boolean always evaluates to true [-Wtautological-constant-compare] cx18_call_hw(cx, CX18_HW_GPIO_RESET_CTRL, ^ drivers/media/pci/cx18/cx18-cards.h:18:37: note: expanded from macro 'CX18_HW_GPIO_RESET_CTRL' #define CX18_HW_GPIO_RESET_CTRL (1 << 6) ^ 1 warning generated. This warning happens because the shift operation is implicitly converted to a boolean in v4l2_device_mask_call_all before being negated. This can be solved by just comparing the mask result to 0 explicitly so that there is no boolean conversion. The ultimate goal is to enable -Wtautological-compare globally because there are several subwarnings that would be helpful to have. For visual consistency and avoidance of these warnings in the future, all of the implicitly boolean conversions in the v4l2_device macros are converted to explicit ones as well.

media: v4l2-rect.h: fix v4l2_rect_map_inside() top/left adjustments

2020-02-11T12:35:14Z

commit f51e50db4c20d46930b33be3f208851265694f3e upstream. boundary->width and boundary->height are sizes relative to boundary->left and boundary->top coordinates, but they were not being taken into consideration to adjust r->left and r->top, leading to the following error: Consider the follow as initial values for boundary and r: struct v4l2_rect boundary = { .left = 100, .top = 100, .width = 800, .height = 600, } struct v4l2_rect r = { .left = 0, .top = 0, .width = 1920, .height = 960, } calling v4l2_rect_map_inside(&r, &boundary) was modifying r to: r = { .left = 0, .top = 0, .width = 800, .height = 600, } Which is wrongly outside the boundary rectangle, because: v4l2_rect_set_max_size(r, boundary); // r->width = 800, r->height = 600 ... if (r->left + r->width > boundary->width) // true r->left = boundary->width - r->width; // r->left = 800 - 800 if (r->top + r->height > boundary->height) // true r->top = boundary->height - r->height; // r->height = 600 - 600 Fix this by considering top/left coordinates from boundary.

Separate the i2c helpers to v4l2-i2c.c, in order to get rid of the ifdefery. No functional changes intended, this is just a cosmetic change to organize the code better. Given I2C is a tristate symbol, a hidden boolean symbol is introduced, to make the conditional build easier.
