[PATCH 0/6] reduce number of warnings being disabled

[PATCH 0/6] reduce number of warnings being disabled

[Bruce Richardson]

for historical reasons, many drivers had extra warnings disabled,
especially in their base code directory. Many, but not all, of these
warning disabling flags are unnecessary so remove as many as we can.

Bruce Richardson (6):
  net/i40e/base: remove warning disable flags
  net/ice/base: remove warning disable flag
  net/e1000/base: remove warning disable flags
  net/iavf: remove warning disable flag
  net/fm10k/base: remove warning disable flags
  common/idpf/base: remove warning disable flags

[PATCH 1/6] net/i40e/base: remove warning disable flags

[Bruce Richardson]

The i40e base code driver has a number of unnecessary warning disabling
flags. We can remove three flags warning about variable format errors.
In the process, simplify the list to one flag per line.

[PATCH 2/6] net/ice/base: remove warning disable flag

[Bruce Richardson]

The -Wno-unused-value flag is not needed for building the base code, so
remove that flag from the list of warnings to disable.
