> Unfortunately, after applying these four patches it doesn't work for me. Your patch disables firmware loading at dvb-frontends/si2168.c:449 while my original one disabled it at tuners/si2157.c:554: case SI_BOGUS: dev_info(&client->dev, "bogus chip version, trying with no firmware\n"); fw_name = NULL; According to my dmesg the following chip is found: [ 141.726488] si2157 10-0063: found a 'Silicon Labs Si2147-A30' [ 141.777647] si2157 10-0063: firmware version: 3.0.5 So according to: case SI2147_A30: case SI2146_A10: fw_name = NULL; it should work. Hmmm. g
