spi: fsl-qspi: Fix double cleanup in probe error path

2025-07-06T09:01:50Z

[ Upstream commit 5d07ab2a7fa1305e429d9221716582f290b58078 ] Commit 40369bfe717e ("spi: fsl-qspi: use devm function instead of driver remove") introduced managed cleanup via fsl_qspi_cleanup(), but incorrectly retain manual cleanup in two scenarios: - On devm_add_action_or_reset() failure, the function automatically call fsl_qspi_cleanup(). However, the current code still jumps to err_destroy_mutex, repeating cleanup. - After the fsl_qspi_cleanup() action is added successfully, there is no need to manually perform the cleanup in the subsequent error path. However, the current code still jumps to err_destroy_mutex on spi controller failure, repeating cleanup. Skip redundant manual cleanup calls to fix these issues.

btrfs: fix use-after-free on inode when scanning root during em shrinking

2025-07-06T09:01:50Z

[ Upstream commit 59f37036bb7ab3d554c24abc856aabca01126414 ] At btrfs_scan_root() we are accessing the inode's root (and fs_info) in a call to btrfs_fs_closing() after we have scheduled the inode for a delayed iput, and that can result in a use-after-free on the inode in case the cleaner kthread does the iput before we dereference the inode in the call to btrfs_fs_closing(). Fix this by using the fs_info stored already in a local variable instead of doing inode->root->fs_info.

When there is no active zone available, btrfs_reserve_extent() returns -EAGAIN. In this case, we have two reactions. (1) If the given range is never allocated, we can only wait for someone to finish a zone, so wait on BTRFS_FS_NEED_ZONE_FINISH bit and retry afterward. (2) Or, if some allocations are already done, we must bail out and let the caller to send IOs for the allocation. This is because these IOs may be necessary to finish a zone. The commit 06f364284794 ("btrfs: do proper folio cleanup when cow_file_range() failed") moved the unlock code from the inside of the loop to the outside. So, previously, the allocated extents are unlocked just after the allocation and so before returning from the function. However, they are no longer unlocked on the case (2) above. That caused the hang issue. Fix the issue by modifying the 'end' to the end of the allocated range. Then, we can exit the loop and the same unlock code can properly handle the case.

ALSA: hda/realtek: Bass speaker fixup for ASUS UM5606KA

[ Upstream commit be8cd366beb80c709adbc7688ee72750f5aee3ff ] This patch applies the ALC294 bass speaker fixup (ALC294_FIXUP_BASS_SPEAKER_15), previously introduced in commit a7df7f909cec ("ALSA: hda: improve bass speaker support for ASUS Zenbook UM5606WA"), to the ASUS Zenbook UM5606KA. This hardware configuration matches ASUS Zenbook UM5606WA, where DAC NID 0x06 was removed from the bass speaker (NID 0x15), routing both speaker pins to DAC NID 0x03. This resolves the bass speaker routing issue, ensuring correct audio output on ASUS UM5606KA.

arm64: dts: rockchip: Add avdd HDMI supplies to RockPro64 board dtsi

2025-07-06T09:01:49Z

[ Upstream commit bd1c959f37f384b477f51572331b0dc828bd009a ] Add missing "avdd-0v9-supply" and "avdd-1v8-supply" properties to the "hdmi" node in the Pine64 RockPro64 board dtsi file. To achieve this, also add the associated "vcca_0v9" regulator that produces the 0.9 V supply, [1][2] which hasn't been defined previously in the board dtsi file. This also eliminates the following warnings from the kernel log: dwhdmi-rockchip ff940000.hdmi: supply avdd-0v9 not found, using dummy regulator dwhdmi-rockchip ff940000.hdmi: supply avdd-1v8 not found, using dummy regulator There are no functional changes to the way board works with these additions, because the "vcc1v8_dvp" and "vcca_0v9" regulators are always enabled, [1][2] but these additions improve the accuracy of hardware description. These changes apply to the both supported hardware revisions of the Pine64 RockPro64, i.e. to the production-run revisions 2.0 and 2.1.
