X-Git-Tag: v2.6.22-rc1~1118^2~61
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=66623a0419da2bae2efab40a46018faacce2e3aa;p=linux-2.6

V4L/DVB (5480): Fix cx88_print_irqbits calls to use ARRAY_SIZE

cx88_print_irqbits were expecting a string pointer with 32 bytes. Better
to pass the string size and use ARRAY_SIZE on its calls.
