Subject: Adding a function pointer to mtd_info struct
Date: Wed, 23 Jan 2008 09:28:13 -0800 (PST) [thread overview]
Message-ID: <63159.87126.qm@web43145.mail.sp1.yahoo.com> (raw)
I am trying to add some new features in my kernel to cfi_cmd_0001.c for a test chip.
I added a new field to the mtd_info struct in mtd.h and inserted the function
pointer into the mtd->overwrite field I added in cfi_cmd_0001.c, but when I try to
use mtd->overwrite in mtdblock.c the pointer is set to NULL.
In the mtd_info struct in include/mtd/mtd.h I addded:
int (*overwrite) (struct mtd_info *mtd, loff_t to, size_t len, size_t *retlen,
const u_char *buf);
In cfi_cmd_0001.c I added:
mtd->overwrite = cfi_intelext_overwrite_buffers;
What file or field do I need to modify to make new function accessible from
mtdblock.c?
