Ah, that's why. Could be documented:
static int debug_fcp_opcode_flag_set(unsigned int opcode,
const u8 *data, int length)
{
switch (opcode) {
case AVC_OPCODE_VENDOR: break;
case AVC_OPCODE_READ_DESCRIPTOR: return avc_debug & AVC_DEBUG_READ_DESCRIPTOR;
case AVC_OPCODE_DSIT: return avc_debug & AVC_DEBUG_DSIT;
case AVC_OPCODE_DSD: return avc_debug & AVC_DEBUG_DSD;
default: goto unknown_opcode;
}
if (length < 7 ||
data[3] != SFE_VENDOR_DE_COMPANYID_0 ||
data[4] != SFE_VENDOR_DE_COMPANYID_1 ||
data[5] != SFE_VENDOR_DE_COMPANYID_2)
goto unknown_opcode;
switch (data[6]) {
case SFE_VENDOR_OPCODE_REGISTER_REMOTE_CONTROL: return avc_debug & AVC_DEBUG_REGISTER_REMOTE_CONTROL;
case SFE_VENDOR_OPCODE_LNB_CONTROL: return avc_debug & AVC_DEBUG_LNB_CONTROL;
case SFE_VENDOR_OPCODE_TUNE_QPSK: return avc_debug & AVC_DEBUG_TUNE_QPSK;
case SFE_VENDOR_OPCODE_TUNE_QPSK2: return avc_debug & AVC_DEBUG_TUNE_QPSK2;
case SFE_VENDOR_OPCODE_HOST2CA: return avc_debug & AVC_DEBUG_HOST2CA;
case SFE_VENDOR_OPCODE_CA2HOST: return avc_debug & AVC_DEBUG_CA2HOST;
}
unknown_opcode: /* should never happen, log it */
return 1;
}
By the way, from here it looks as if your MUA converted tabs to spaces.
In your other patch too.
