Subject: media: si2157: fix bandwidth stored in dev Author: Robert Schlabbach <[email protected]> Date: Thu Jan 6 23:51:39 2022 +0100 Make digital tuning store the bandwidth in Hz in the private dev struct, rather than the hardware-specific bandwidth property code, so that the get_bandwidth() function returns the bandwidth in Hz, just as it already does when using analog tuning.
