[PATCH] arm64: dts: qcom: sa8775p: Fix the size of 'addr_space' regions

by Manivannan Sadhasivam

For both the controller instances, size of the 'addr_space' region should be 0x1fe00000 as per the hardware memory layout. Otherwise, endpoint drivers cannot request even reasonable BAR size of 1MB.

[PATCH] mmc: core: Further prevent card detect during shutdown

by Ulf Hansson

Disabling card detect from the host's ->shutdown_pre() callback turned out to not be the complete solution. More precisely, beyond the point when the mmc_bus->shutdown() has been called, to gracefully power off the card, we need to prevent card detect. Otherwise the mmc_rescan work may poll for the card with a CMD13, to see if it's still alive, which then will fail and hang as the card has already been powered off. To fix this problem, let's disable mmc_rescan prior to power off the card during shutdown.

[PATCH 5.4 0/1] Address CVE-2024-49974

by cel＠kernel.org

From: Chuck Lever <chuck.lever(a)oracle.com> Backport the upstream patch that disables background NFSv4.2 COPY operations. Unlike later LTS kernels, the patches that limit the number of background COPY operations do not apply at all to v5.4. Because there is no support for server-to-server COPY in v5.4, disabling background COPY operations should not be noticeable.

[PATCH v4] regmap: detach regmap from dev on regmap_exit

by Cosmin Tanislav

At the end of __regmap_init(), if dev is not NULL, regmap_attach_dev() is called, which adds a devres reference to the regmap, to be able to retrieve a dev's regmap by name using dev_get_regmap(). When calling regmap_exit, the opposite does not happen, and the reference is kept until the dev is detached. Add a regmap_detach_dev() function and call it in regmap_exit() to make sure that the devres reference is not kept.

[PATCH AUTOSEL 4.19 01/21] drm/radeon/r600_cs: Fix possible int overflow in r600_packet3_check()

by Sasha Levin

From: Igor Artemiev <Igor.A.Artemiev(a)mcst.ru> [ Upstream commit a1e2da6a5072f8abe5b0feaa91a5bcd9dc544a04 ] It is possible, although unlikely, that an integer overflow will occur when the result of radeon_get_ib_value() is shifted to the left. Avoid it by casting one of the operands to larger data type (u64). Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE.

[PATCH 0/9] media: uvcvideo: Implement Granular Power Saving

by Ricardo Ribalda

Right now we power-up the device when a user open() the device and we power it off when the last user close() the first video node. This behaviour affects the power consumption of the device is multiple use cases, such as: - Polling the privacy gpio - udev probing the device This patchset introduces a more granular power saving behaviour where the camera is only awaken when needed. It is compatible with asynchronous controls. While developing this patchset, two bugs were found. The patchset has been developed so these fixes can be taken independently.
