dpaa_eth: Remove unnecessary boolean expression in dpaa_get_headroom
commit 7395f62d upstream. Clang warns: drivers/net/ethernet/freescale/dpaa/dpaa_eth.c:2860:9: warning: converting the result of '?:' with integer constants to a boolean always evaluates to 'true' [-Wtautological-constant-compare] return DPAA_FD_DATA_ALIGNMENT ? ALIGN(headroom, ^ drivers/net/ethernet/freescale/dpaa/dpaa_eth.c:131:34: note: expanded from macro 'DPAA_FD_DATA_ALIGNMENT' \#define DPAA_FD_DATA_ALIGNMENT (fman_has_errata_a050385() ? 64 : 16) ^ 1 warning generated. This was exposed by commit 3c68b8ff ("dpaa_eth: FMan erratum A050385 workaround") even though it appears to have been an issue since the introductory commit 9ad1a374 ("dpaa_eth: add support for DPAA Ethernet") since DPAA_FD_DATA_ALIGNMENT has never been able to be zero. Just replace the whole boolean expression with the true branch, as it is always been true.
