media: ttpci: improve printing of encoded MAC address
When loading the budget_av driver for ie. a KNC1 DVB-C TDA10024 card, which makes use of the ttpci eeprom check functionality (that always fails on these cards, but that's no issue at all), this is printed to the kernel log: [ 10.497333] saa7146 (0): dma buffer size 192512 [ 10.497335] dvbdev: DVB: registering new adapter (KNC1 DVB-C TDA10024) [ 10.545007] adapter failed MAC signature check [ 10.545009] encoded MAC from EEPROM was [ 10.545010] ff: [ 10.545011] ff: [ 10.545011] ff: ... [ 10.545021] ff [ 10.832422] budget_av: KNC1-4: MAC addr = 00:09:d6:6d:b3:be with the 'ff' being repeated for a total of 20 times. Improve that by using the %*phC format specifier instead dprintk()'ing every byte of the encoded MAC separately. This obsoletes the int i, and the kernel log looks cleaner: [ 3234.383153] saa7146 (0): dma buffer size 192512 [ 3234.383154] dvbdev: DVB: registering new adapter (KNC1 DVB-C TDA10024) [ 3234.428745] adapter failed MAC signature check [ 3234.428747] encoded MAC from EEPROM was ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff [ 3234.728194] budget_av: KNC1-0: MAC addr = 00:09:d6:6d:b3:be Signed-off-by: Daniel Scheller <d.scheller@gmx.net> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
