If anyone has any objections, please let me know. ------------------ From: Salah Triki commit d380bf5f94a892e546d9a94e8557ad866b043a2a upstream. When setting the sampling frequency, the check for `base_freq / 2` is followed by an independent `if` statement for `base_freq / 4`. If `val` equals `base_freq / 2`, the second check fails and falls through to the `else if (val != base_freq)` branch, returning `-EINVAL` erroneously. Fix this by chaining the checks with `else if`.
