2022-07-24i2c: cadence: Support PEC for SMBus block readLars-Peter Clausen
SMBus packet error checking (PEC) is implemented by appending one additional byte of checksum data at the end of the message. This provides additional protection and allows to detect data corruption on the I2C bus. SMBus block reads support variable length reads. The first byte in the read message is the number of available data bytes. The combination of PEC and block read is currently not supported by the Cadence I2C driver. * When PEC is enabled the maximum transfer length for block reads increases from 33 to 34 bytes. * The I2C core smbus emulation layer relies on the driver updating the `i2c_msg` `len` field with the number of received bytes. The updated length is used when checking the PEC. Add support to the Cadence I2C driver for handling SMBus block reads with PEC. To determine the maximum transfer length uses the initial `len` value of the `i2c_msg`. When PEC is enabled this will be 2, when it is disabled it will be 1. Once a read transfer is done also increment the `len` field by the amount of received data bytes. This change has been tested with a UCM90320 PMBus power monitor, which requires block reads to access certain data fields, but also has PEC enabled by default.

This driver is the only caller of vfio_pin/unpin_pages that might pass in a non-contiguous PFN list, but in many cases it has a contiguous PFN list to process. So letting VFIO API handle a non-contiguous PFN list is actually counterproductive. Add a pair of simple loops to pass in contiguous PFNs only, to have an efficient implementation in VFIO.

2022-07-23vfio: Make vfio_unpin_pages() return voidNicolin Chen
There's only one caller that checks its return value with a WARN_ON_ONCE, while all other callers don't check the return value at all. Above that, an undo function should not fail. So, simplify the API to return void by embedding similar WARN_ONs. Also for users to pinpoint which condition fails, separate WARN_ON lines, yet remove the "driver->ops->unpin_pages" check, since it's unreasonable for callers to unpin on something totally random that wasn't even pinned. And remove NULL pointer checks for they would trigger oops vs. warnings. Note that npage is already validated in the vfio core, thus drop the same check in the type1 code.

2022-07-22net: usb: ax88179_178a: move priv to driver_privJustin Chen
We need more space to save WoL context. So lets allocate memory for ax88179_data instead of using struct usbnet data field which only supports 5 words. We continue to use the struct usbnet data field for multicast filters. However since we no longer have the private data stored there, we can shift it to the beginning.
