These two variables actually were declared in several places.
The variables are used in several files.
I've fixed "easycap_debug" so it gets declared in one place only and included properly.
For "easycap_gain" made it static and I created added a
->gain member to the easycap struct. This seems cleaner than using a
global variable and later on we may make this controlable via sysfs.

With all the patches we have queued in the BKL removal tree, only a
few dozen modules are left that actually rely on the BKL, and even
there are lots of low-hanging fruit. We need to decide what to do
about them, this patch illustrates one of the options:
Every user of the BKL is marked as 'depends on BKL' in Kconfig,
and the CONFIG_BKL becomes a user-visible option. If it gets
disabled, no BKL using module can be built any more and the BKL
code itself is compiled out.
The one exception is file locking, which is practically always
enabled and does a 'select BKL' instead. This effectively forces
CONFIG_BKL to be enabled until we have solved the fs/lockd
mess and can apply the patch that removes the BKL from fs/locks.c.
