2023-12-04ASoC: ops: add correct range check for limiting volumeSrinivas Kandagatla
Volume can have ranges that start with negative values, ex: -84dB to +40dB. Apply correct range check in snd_soc_limit_volume before setting the platform_max. Without this patch, for example setting a 0dB limit on a volume range of -84dB to +40dB would fail.

2023-12-04drm/i915/dsi: Use devm_gpiod_get() for all GPIOsHans de Goede
soc_gpio_set_value() already uses devm_gpiod_get(), lets be consistent and use devm_gpiod_get() for all GPIOs. This allows removing the intel_dsi_vbt_gpio_cleanup() function, which only function was to put the GPIO-descriptors.

2023-12-04mlxbf-bootctl: correctly identify secure boot with development keysDavid Thompson
The secure boot state of the BlueField SoC is represented by two bits: 0 = production state 1 = secure boot enabled 2 = non-secure (secure boot disabled) 3 = RMA state There is also a single bit to indicate whether production keys or development keys are being used when secure boot is enabled. This single bit (specified by MLXBF_BOOTCTL_SB_DEV_MASK) only has meaning if secure boot state equals 1 (secure boot enabled). The secure boot states are as follows: - “GA secured” is when secure boot is enabled with official production keys. - “Secured (development)” is when secure boot is enabled with development keys. Without this fix “GA Secured” is displayed on development cards which is misleading. This patch updates the logic in "lifecycle_state_show()" to handle the case where the SoC is configured for secure boot and is using development keys.

2023-12-04r8152: Hold the rtnl_lock for all of resetDouglas Anderson
As of commit d9962b0d4202 ("r8152: Block future register access if register access fails") there is a race condition that can happen between the USB device reset thread and napi_enable() (not) getting called during rtl8152_open(). Specifically: * While rtl8152_open() is running we get a register access error that's _not_ -ENODEV and queue up a USB reset. * rtl8152_open() exits before calling napi_enable() due to any reason (including usb_submit_urb() returning an error). In that case: * Since the USB reset is perform in a separate thread asynchronously, it can run at anytime USB device lock is not held - even before rtl8152_open() has exited with an error and caused __dev_open() to clear the __LINK_STATE_START bit. * The rtl8152_pre_reset() will notice that the netif_running() returns true (since __LINK_STATE_START wasn't cleared) so it won't exit early. * rtl8152_pre_reset() will then hang in napi_disable() because napi_enable() was never called. We can fix the race by making sure that the r8152 reset routines don't run at the same time as we're opening the device. Specifically we need the reset routines in their entirety rely on the return value of netif_running(). The only way to reliably depend on that is for them to hold the rntl_lock() mutex for the duration of reset. Grabbing the rntl_lock() mutex for the duration of reset seems like a long time, but reset is not expected to be common and the rtnl_lock() mutex is already held for long durations since the core grabs it around the open/close calls.
