[PATCH] 2.5.19 : drivers/mtd/nftlcore.c

[Frank Davis]

Hello all,
  The following patch fixes a few compiler warnings, as well as provides 
blk_init_queue() with the appropriate arguments. Please review for 
inclusion. Thanks to Jens Axboe for fixing the casting hack in 
the previous version of this patch. 

Regards,
Frank
