Staging: easycap: fix sparse warnings for module parameters
easycap_main.c:34:5: warning: symbol 'easycap_debug' was not declared. Should it be static? easycap_main.c:36:5: warning: symbol 'easycap_gain' was not declared. Should it be static? 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.
