64-bit issues?

[GoogleCodeExporter]

I am trying to modify the eeprom of an Intel 5100AGN miniPCIe card to work in 
my HP laptop. However, I am failing at the first step: getting a eeprom dump of 
the card.

I am building iwleeprom on an Intel Atom D510MO board, and I know the minipcie 
connection is good, since I'm using it normally for a Broadcom decoder and 
that's working fine.

System is Arch Linux, 64 bit:
Linux brain 3.2.9-1-ARCH #1 SMP PREEMPT Thu Mar 1 09:31:13 CET 2012 x86_64 
GNU/Linux
# gcc --version
gcc (GCC) 4.7.0 20120505 (prerelease)

After checking out revision 37, I see some warnings:

# make
gcc -Wall -O2 -o iwleeprom iwleeprom.c
iwleeprom.c:109:3: warning: data definition has no type or storage class 
[enabled by default]
iwleeprom.c:109:3: warning: type defaults to 'int' in declaration of 'nodev' 
[-Wimplicit-int]
iwleeprom.c:110:3: warning: type defaults to 'int' in declaration of 
'preserve_mac' [-Wimplicit-int]
iwleeprom.c:111:3: warning: type defaults to 'int' in declaration of 
'preserve_calib' [-Wimplicit-int]
iwleeprom.c: In function 'init_dump':
iwleeprom.c:251:2: warning: format '%Ld' expects argument of type 'long long 
int', but argument 3 has type 'size_t' [-Wformat]

Seems OK after building:

# ./iwleeprom
Supported devices detected: 
  [1] 0000:02:00.0 [RW] WiFi Link 5100 (8086:4232, 8086:1321)

Using device 0000:02:00.0 [RW] WiFi Link 5100 
No file names given or patch option selected!
No EEPROM actions will be performed, just write-enable test

But trying to dump fails and results in a zero-byte file:

# ./iwleeprom -D 1 -d 0000:02:00.0  -o eeprom.bin
debug level: 1

Try to increase delay in eeprom_read16(). It works for me after replacing 
usleep(50) with usleep(10000)

The compile-time warnings are due to a couple of typos in the code. Please 
apply the attached patch to resolve them.
