Subject: [U-Boot-Users] [patch] do not use cmd_reset uninitialized in cfi_flash.c
Date: Mon, 28 Jan 2008 22:27:05 -0500	[thread overview]
Message-ID: <200801282227.06426.vapier@gentoo.org> (raw)

The cmd_reset member of the flash info struct is not initialized until the
specific cmdset function is called.  This normally happens by:
 flash_get_size -> flash_detect_cfi -> cmdset_*_init
That means we cannot use cmd_reset inside of the cfi detection functions.
