Subject: [PATCH] staging: line6: use kstrtoint() instead of simple_strtoul()

From: "Laurent Navet [Mali]" <[email protected]>

staging: line6: pcm.c
call to obsolete simple_strtoul() function is replaced
by kstrtoint() in pcm_set_impulse_period().
Also check the return code.

This uses spaces instead of tabs. Run scripts/checkpatch.pl over
the patch before submitting.

Put a blank line here between the declarations and the code.

I see that you copied "rv" from the other places in the file and
generally matching the context is good, but in this case I think
"rv" is non-standard. Normally we would use "ret" or "rc".

Could you fix up those small details and resend?
