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
