because the dib*_state structs are large and they are alloc'd on the stack.
This patch moves the structures off the stack.
Hi Prarit,
Thanks for the patch, but I've received two patches to fix the same thing some
time ago.
Unfortunately, it took a long time to be merged, since I was waiting for the
driver
maintainer's ack. It is at those changesets:
http://git.linuxtv.org/v4l-dvb.git?a=commit;h=65483f7e5f3e169ea038de26068395231dd3b13b

Oops! Sorry about that Mauro :( -- I didn't realize there was another
git tree to check. Just curious -- is the one listed in MAINTAINERS
still active?
I also noticed that the cxusb driver doesn't check the return value from
dib7000p_i2c_enumeration().
Randy's patch also added a test for it, but without the warning printk. It may
be a good
idea to have that warning. So, please be free to send it as a separate patch if
you also
think so.
Sure I'll do that shortly (after checking out the above tree ;) ).
