Subject: [media] lmedm04 ver 1.99 support for m88rs2000 v2
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4f3b7fed467c23bbc99436d8e8b8e4bdb99a09e1;p=linux-beck.git

[media] lmedm04 ver 1.99 support for m88rs2000 v2

Support for m88rs2000 module.

The driver also attempts to overcome occasional lock problems.

Call backs are now used for read_status, signal level and SNR.
