2022-09-28random: avoid reading two cache lines on irq randomnessJason A. Donenfeld
In order to avoid reading and dirtying two cache lines on every IRQ, move the work_struct to the bottom of the fast_pool struct. add_ interrupt_randomness() always touches .pool and .count, which are currently split, because .mix pushes everything down. Instead, move .mix to the bottom, so that .pool and .count are always in the first cache line, since .mix is only accessed when the pool is full.

2022-09-28pwm: sysfs: Replace sprintf() with sysfs_emit()Andy Shevchenko
While the uses in this code are unproblematic, it's generally safer for sysfs outputs to use the new sysfs_emit() helper instead of raw calls to sprintf() and friends. This also has the benefit of annotating the uses, which makes them easier to audit and potentially use them to generate sysfs documentation from them. This patch replaces existing sprintf() calls straightforwardly with the new helper.

2022-09-28mfd: core: Delete corresponding OF node entries from list on MFD removalMichal Oleszczyk
When we consider MFD which implements hotplug (e.g. USB hotplug driver based on product and vendor IDs) functionality it turns out that its sub-devices are correctly matched with corresponding device tree nodes only at the first time. When physical device reboots or is replugged (and MFD driver is disconnected and probed back again) all sub-devices fails in mfd_add_device() with error 'Failed to locate of_node'. The reason of that behavior is that when any MFD sub-device is created for the first time (and matched with device tree node) it is added to the mfd_of_node_list. It looks like this list is never cleaned even if devices added there are intentionally removed from the system. So when MFD device is replugged and all sub-devices are matched with their device tree nodes again they fail as matched nodes already exist in mfd_of_node_list. In other words current implementation does not support MFD with hotplug feature. This commit extends MFD core for hotplugging support by removing appropriate OF node entry from mfd_of_node_list when corresponding device is removed from the system. Thanks to that when device is added once again it can be matched with its device tree node successfully.

Use sub-function of_compatible during probe, instead of using the node name. The code should not rely on the node names during probe, in addition to that the previously hard-coded node names are not compliant to the latest naming convention (they are not generic and they use underscores), and it was broken by mistake already once [1].

2022-09-28mfd: stmpe: Remove rotator block from probeFrancesco Dolcini
Remove rotator block from probe, it is not used in any device tree file, there is no related cell defined, it's just dead non-working code with no of_compatible for it. This is a preliminary change to allow probing by of_compatible and not by a fixed name.

2022-09-28drm/bridge: lt8912b: fix corrupted image outputFrancesco Dolcini
Correct I2C address for the register list in lt8912_write_lvds_config(), these registers are on the first I2C address (0x48), the current function is just writing garbage to the wrong registers and this creates multiple issues (artifacts and output completely corrupted) on some HDMI displays. Correct I2C address comes from Lontium documentation and it is the one used on other out-of-tree LT8912B drivers [1].
