Hi,
I noticed this warnings on current git with gcc 4.2.1
....
drivers/mtd/devices/doc2000.c: In function 'doc_read':
drivers/mtd/devices/doc2000.c:635: warning: the address of 'eccbuf' will always evaluate as 'true'
drivers/mtd/devices/doc2000.c: In function 'doc_write':
drivers/mtd/devices/doc2000.c:899: warning: the address of 'eccbuf' will always evaluate as 'true'
....
This patch fixes it but maybe there is a better way to do it.
