Subject: FIX-Problem: use counter armflash.c
Date: Wed, 02 May 2001 17:36:06 +0200 [thread overview]
Message-ID: <3AF02966.9689ABA5@convergence.de> (raw)
Hi list,
I was playing with mtd's on an arm integrator board.
I think I found a bug in the clean up sequence of the module armflash.
The use counter never counts down when I unload the module armflash.
Here is my patch to correct this behavior:
---cut---
513,529d512
< int i;
< struct mtd_info *ret, *mtd;
<
< for (i=0; i < MAX_MTD_DEVICES; i++)
< {
< mtd = NULL;
< ret = __get_mtd_device(mtd, i);
<
< // printk("count down %d usecount %d\n",i, ret);
< if(ret!=NULL)
< {
< if(del_mtd_device(ret))
< {
< printk("cleanup %d failed\n",i);
< }
< }
< }
---cut---
There is another usecounter problem in armflash. In the afs_cfi_init()
function the
function do_map_probe() is called. After this call the usecount
of the module cfi_cmdset_0001 is incremented and would never be
decremented.
How can I fix this behaviour?
Is there anybody who is working with mtd's on arm-integrator?
regards
Frank
