2020-09-25intel: handle unused assignmentsJesse Brandeburg
Remove variables that were storing a return value from a register read or other read, where the return value wasn't used. Those conversions to remove the lvalue of the assignment should be safe because the readl memory mapped reads are marked volatile and should not be optimized out without an lvalue (I suspect a very long time ago this wasn't guaranteed as it is today). These changes are part of a separate patch to make it easier to review. Warnings Fixed: .../intel/e100.c:2596:9: warning: variable ‘err’ set but not used [-Wunused-but-set-variable] .../intel/ixgb/ixgb_hw.c:101:6: warning: variable ‘icr_reg’ set but not used [-Wunused-but-set-variable] .../intel/ixgb/ixgb_hw.c:277:6: warning: variable ‘ctrl_reg’ set but not used [-Wunused-but-set-variable] .../intel/ixgb/ixgb_hw.c:952:15: warning: variable ‘temp_reg’ set but not used [-Wunused-but-set-variable] .../intel/ixgb/ixgb_hw.c:1164:7: warning: variable ‘mdio_reg’ set but not used [-Wunused-but-set-variable] .../intel/e1000/e1000_hw.c:132:6: warning: variable ‘ret_val’ set but not used [-Wunused-but-set-variable] .../intel/e1000/e1000_hw.c:380:6: warning: variable ‘icr’ set but not used [-Wunused-but-set-variable] .../intel/e1000/e1000_hw.c:2378:6: warning: variable ‘signal’ set but not used [-Wunused-but-set-variable] .../intel/e1000/e1000_hw.c:2374:6: warning: variable ‘ctrl’ set but not used [-Wunused-but-set-variable] .../intel/e1000/e1000_hw.c:2373:6: warning: variable ‘rxcw’ set but not used [-Wunused-but-set-variable] .../intel/e1000/e1000_hw.c:4678:15: warning: variable ‘temp’ set but not used [-Wunused-but-set-variable] Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: David S.

2018-04-27net: intel: Cleanup the copyright/license headersJeff Kirsher
After many years of having a ~30 line copyright and license header to our source files, we are finally able to reduce that to one line with the advent of the SPDX identifier. Also caught a few files missing the SPDX license identifier, so fixed them up.

2011-09-23ixgb: eliminate checkstack warningsJesse Brandeburg
Really trivial fix, use kmalloc/kfree instead of stack space. use static const instead of const to further reduce stack usage.
