CR ENGR00053173 Fix SDMA Mask Value In Suspend Routine
Patch for CR ENGR00053173: Fix SDMA mask value in suspend routine. Use the correct mask value to get the current SDMA State. Applies to linux 2.6.22 kernel for MX3 platforms. http://www.bitshrine.org/gpp/linux-2.6.22-mx-CR-ENGR00053173-Fix-SDMA-Mask-Value-In-Sus.patch
