module: Fix ERRORs reported by checkpatch.pl
Checkpatch reports following errors:
ERROR: do not use assignment in if condition
+ if ((colon = strnchr(name, MODULE_NAME_LEN, ':')) != NULL) {
ERROR: do not use assignment in if condition
+ if ((mod = find_module_all(name, colon - name, false)) != NULL)
ERROR: do not use assignment in if condition
+ if ((ret = find_kallsyms_symbol_value(mod, name)) != 0)
ERROR: do not initialise globals to 0
+int modules_disabled = 0;
Fix them.
The following one has to remain, because the condition has to be evaluated
multiple times by the macro wait_event_interruptible_timeout().
