Zijun Hu 87ac021c84 char: misc: Does not request module for miscdevice with dynamic minor 
[ Upstream commit 1ba0fb42aa ]

misc_open() may request module for miscdevice with dynamic minor, which
is meaningless since:

- The dynamic minor allocated is unknown in advance without registering
  miscdevice firstly.
- Macro MODULE_ALIAS_MISCDEV() is not applicable for dynamic minor.

Fix by only requesting module for miscdevice with fixed minor.
