Subject: 2.6.30 oops with acpi/button

Hi Len & Bjorn,
 	I've not had time to go back to it but with 2.6.30 I get an oops 
when I close the lid on my HP Compaq 6910p laptop. I see you removed some 
null pointer checks.. perhaps tha tis why? Here is the oops extracted from 
my log file. If you want me to test a patch let me know. I'm about to try 
2.6.30.1 but I don't see anything in the ChangeLog that is likely to make 
a difference.
 	I've gone back to 2.6.29.4 where it is fine. I tried unloading the 
"button" module first but in that case my laptop locked up without an 
oops. No flashing num/caps lock or anything, just froze when I close the 
lid. The version of button.c from 2.6.29.4  doesn't compile in the 2.6.30 
tree;

drivers/acpi/button.c: In function ‘acpi_button_add_fs’:
drivers/acpi/button.c:203: error: ‘struct proc_dir_entry’ has no member 
named ‘owner’
drivers/acpi/button.c:208: error: ‘struct proc_dir_entry’ has no member 
named ‘owner’
drivers/acpi/button.c: In function ‘acpi_button_init’:
drivers/acpi/button.c:525: error: ‘struct proc_dir_entry’ has no member 
named ‘owner’

 	Any ideas?

 						regards,

 						Stephen.
