[GitBox]

davids5 opened a new pull request #1604:
URL: https://github.com/apache/incubator-nuttx/pull/1604


   ## Summary
   
      When CONFIG_MMCSD_MULTIBLOCK_DISABLE is lit, all SD
      read/write failed. The function return the number of
      blocks in `ret`, set on entry to nsectors. That was
      then wiped out by using the ret for the mmcsd_takesem.
   
      Since the code had many path setting return, the choices for
      the fix could have been add a new varaible or simple init it
      were used. I choose the latter.
   
   ## Impact
   
   Since 2020-03-31 SD cards not using multi block (i.e with 
CONFIG_MMCSD_MULTIBLOCK_DISABLE) are broken.
    
   ## Testing
   
   was done on nxp_fmuk66-v3
