2025-12-29dt-bindings: misc: qcom,fastrpc: Add compatible for KaanapaliKumari Pallavi
Kaanapali introduces changes in DSP IOVA layout and CDSP DMA addressing that differ from previous SoCs. The SID field moves within the physical address, and CDSP now supports a wider DMA range, requiring updated sid_pos and DMA mask handling in the driver.

2025-12-29rust_binder: Fix build failure if !CONFIG_COMPATXi Ruoyao
The bindgen utility cannot handle "#define compat_ptr_ioctl NULL" in the C header, so we need to handle this case on our own. Simply skip this field in the initializer when !CONFIG_COMPAT as the SAFETY comment above this initializer implies this is allowed.

2025-12-29platform/x86: samsung-galaxybook: Fix problematic pointer castArmin Wolf
A user reported that reading the charge threshold on his device results in very strange values (like 78497792) being returned. The reason for this seems to be the fact that the driver casts the int pointer to an u8 pointer, leaving the last 3 bytes of the destination uninitialized. Fix this by using a temporary variable instead.

In the function bcm_vk_read(), the pointer entry is checked, indicating that it can be NULL. If entry is NULL and rc is set to -EMSGSIZE, the following code may cause null-pointer dereferences: struct vk_msg_blk tmp_msg = entry->to_h_msg[0]; set_msg_id(&tmp_msg, entry->usr_msg_id); tmp_msg.size = entry->to_h_blks - 1; To prevent these possible null-pointer dereferences, copy to_h_msg, usr_msg_id, and to_h_blks from iter into temporary variables, and return these temporary variables to the application instead of accessing them through a potentially NULL entry.

commit 14374fbb3f06 ("misc: eeprom_93xx46: Add new 93c56 and 93c66 compatible strings") added support for 93xx56 and 93xx66 eeproms, but didn't take into account that the write enable/disable + erase all commands are hardcoded for the 6-bit address of the 93xx46. This commit fixes the command word generation by increasing the number of shifts as the address field grows, keeping the command intact.

2025-12-29pmdomain: mtk-pm-domains: Fix spinlock recursion fix in probeMacpaul Lin
Remove scpsys_get_legacy_regmap(), replacing its usage with of_find_node_with_property(). Explicitly call of_node_get(np) before each of_find_node_with_property() to maintain correct node reference counting. The of_find_node_with_property() function "consumes" its input by calling of_node_put() internally, whether or not it finds a match. Currently, dev->of_node (np) is passed multiple times in sequence without incrementing its reference count, causing it to be decremented multiple times and risking early memory release. Adding of_node_get(np) before each call balances the reference count, preventing premature node release.

2025-12-29arm64: dts: imx94: add basic NETC related nodesWei Fang
The NETC related nodes for i.MX94, this NETC has two PCIe buses, the bus 0 has 1 ENETC instance, one PTP timer, one RCEC and a switch, currently, the switch is not added due to the DT binding and the driver is not ready at the moment. The bus 1 has three ENETC instances, 2 PTP timers, 1 RCEC and one EMDIO. Signed-off-by: Wei Fang <wei.fang@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

2025-12-29crypto: drbg - make drbg_fips_continuous_test() return boolSergey Shtylyov
Currently, drbg_fips_continuous_test() only returns 0 and -EAGAIN, so an early return from the *do*/*while* loop in drbg_get_random_bytes() just isn't possible. Make drbg_fips_continuous_test() return bool instead of *int* (using true instead of 0 and false instead of -EAGAIN). This way, we can further simplify drbg_get_random_bytes()...

2025-12-29crypto: qat - fix duplicate restarting msg during AER errorHarshita Bhilwaria
The restarting message from PF to VF is sent twice during AER error handling: once from adf_error_detected() and again from adf_disable_sriov(). This causes userspace subservices to shutdown unexpectedly when they receive a duplicate restarting message after already being restarted. Avoid calling adf_pf2vf_notify_restarting() and adf_pf2vf_wait_for_restarting_complete() from adf_error_detected() so that the restarting msg is sent only once from PF to VF.
