Commit de47725, first released in 3.2-rc1 removed module.h from some kernel headers. Include it explicitly now. Resolves compilation errors like: error: implicit declaration of function 'try_module_get' error: 'THIS_MODULE' undeclared (first use in this function) error: implicit declaration of function 'module_put' Signed-off-by: Shaun Ruffell <sruffell@digium.com> git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@10361 a0bf4364-ded3-4de4-8d8a-66a801d63aff
