Patchset tweaks bitset operations by changing a constant to unsigned
long, introduces a static compile check and simplifies bitset operations.
Also resolves Coverity CID 1563776.

v2..v3:
* Multiply (sizeof(d->mux_bitset) * BITS_PER_BYTE) to get number
  of bits (thanks Paolo Bonzini for noticing that)
* Rebase on latest master

v1..v2:
  * Rebase on latest master, incorporate review tags.

Roman Penyaev (2):
  chardev/char-mux: shift unsigned long to avoid 32-bit overflow
  chardev/char-mux: make boolean bit check instead of find_next_bit()
