Patch-mainline: v5.14-rc1

References: git-fixes

Remove some unreachable code, so to suppress this warning:

drivers/net/ethernet/marvell/mvpp2/mvpp2_prs.c: In function ‘mvpp2_prs_tcam_first_free’:

drivers/net/ethernet/marvell/mvpp2/mvpp2_prs.c:397:10: warning: comparison is always false due to limited range of data type [-Wtype-limits]

  397 |  if (end >= MVPP2_PRS_TCAM_SRAM_SIZE)

      |          ^~
