I tried the latest svn tip of GCC and it looks like this warning is
quite recent (and I happened to have this driver enabled as a module
in my kernel):

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’
drivers/mtd/devices/doc2001plus.c: In function ‘doc_write’:
drivers/mtd/devices/doc2001plus.c:751: warning: the address of ‘eccbuf’ will always evaluate as ‘true’
