Fix unused variable warning in mlx5_ib_devx.c

2022-07-24T22:40:13+00:00

With clang 15, the following -Werror warning is produced:

    sys/dev/mthca/mthca_cmd.c:662:23: error: variable 'tc' set but not used [-Werror,-Wunused-but-set-variable]
            int ts __unused = 0, tc = 0;
                                 ^

The 'ts' and 'tc' variables are eventually used only in mthca_dbg()
macros, if CONFIG_INFINIBAND_MTHCA_DEBUG is defined. Ensure 'ts' and
'tc' are only declared and used when CONFIG_INFINIBAND_MTHCA_DEBUG is
defined.

mlx4, mthca: Silence warnings about no-op alignment operations

2021-02-11T15:16:59+00:00

Since commit 8fa6abb6f4f64f ("Expose clang's alignment builtins and use
them for roundup2/rounddown2"), clang emits warnings for several
alignment operations in these drivers because the operation is a no-op.
The compiler is arguably being too strict here, but in the meantime
let's silence the warnings by conditionally compiling the alignment
operations.
