2020-01-22staging: wilc1000: move firmware API struct's to separate header fileAjay Singh
It's recommended to keep the 'struct' used for passing data to firmware in separate header file. So added 'fw.h' header file to keep struct's used to pass data to firmware.

2020-01-22staging: wilc1000: remove use of infinite loop conditionsAjay Singh
Avoid the use of 'while (1)' infinite loop conditions. It's not recommended to have infinite loop in kernel code because a small bug can cause never ending loops so use terminator condition as suggested in full driver review [1].

2020-01-22staging: most: net: fix buffer overflowAndrey Shvetsov
If the length of the socket buffer is 0xFFFFFFFF (max size for an unsigned int), then payload_len becomes 0xFFFFFFF1 after subtracting 14 (ETH_HLEN). Then, mdp_len is set to payload_len + 16 (MDP_HDR_LEN) which overflows and results in a value of 2. These values for payload_len and mdp_len will pass current buffer size checks. This patch checks if derived from skb->len sum may overflow. The check is based on the following idea: For any `unsigned V1, V2` and derived `unsigned SUM = V1 + V2`, `V1 + V2` overflows iif `SUM < V1`.

2020-01-21Input: axp20x-pek - respect userspace wakeup configurationSamuel Holland
Unlike most other power button drivers, this driver unconditionally enables its wakeup IRQ. It should be using device_may_wakeup() to respect the userspace configuration of wakeup sources. Because the AXP20x MFD device uses regmap-irq, the AXP20x PEK IRQs are nested off of regmap-irq's threaded interrupt handler. The device core ignores such interrupts, so to actually disable wakeup, we must explicitly disable all non-wakeup interrupts during suspend.
