Subject: [Linux-kernel-mentees] [PATCH v3 1/3] cec-follower: fix bugs for
	tuner emulation
In-Reply-To: <20190924192445.93575-1-c0d1n61at3@gmail.com>

List-Id: <linux-kernel-mentees.lists.linuxfoundation.org>

Fix some typos for tuner emulation:
  - analog_tuner_init() store ana_freq in hex
  - analog_get_nearest_freq() temp variable check
