Jeff Kirsher says: ==================== Intel Wired LAN Driver Fixes 2018-08-23 This series contains bug fixes to the ice driver. Anirudh provides several fixes, starting with static analysis fixes by replacing a bitwise-and with a constant value and replace "magic" numbers with defines. Fixed the control queue processing by removing unnecessary read/writes to registers, as well as getting a accurate value for "pending". Added additional checks to avoid NULL pointer dereferences. Fixed up code formatting issues, by cleaning up code comments and coding style. Bruce cleans up a duplicate check for owner, within the same function. Also cleans up interrupt causes that are not handled or applicable. Fix checkpatch warning about the use of bool in structures due to the wasted space and size of bool, so convert struct members to u8 instead. Jake fixes a number of potential bugs in the reporting of stats via ethtool, by simply reporting all the queue statistics, even for the queues that are not activated. Fixed a compiler warning, as well as make the code a bit cleaner but just using order_base_2() for calculating the power-of-2. Preethi adds a check to avoid a NULL pointer dereference crash during initialization. Brett clarifies the code when it comes to port VLANs and regular VLANs, by renaming defines and field values to match their intended use and purpose. Jesse initializes a variable to avoid garbage values being returned to the caller. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
