   4 Subject: [PATCH] dahdi_echocan_mg2: rename ABS define to PARA_ABS
   5
   6 Rename ABS define to PARA_ABS to fix compilation error with mips 24kc
   7 arch.
   8
   9 This target define in his ASM header a similar define ABS that cause
  10 conflicts and redefinition error for this driver.
  11
  12 Rename ABS to PARA_ABS to better suite the usage as it's abs usage with
  13 value decremented by one if it's the max negative int.
