The prefix suggests the number should be printed in hex, so use
the %x specifier to do that.

Found by using regex suggested by Joe Perches.

It would be best to actually build with your patches installed. This one yields
the following warning:

  CC [M]  drivers/net/wireless/rtlwifi/rtl8192de/fw.o
drivers/net/wireless/rtlwifi/rtl8192de/fw.c: In function ‘_rtl92d_fw_init’:
drivers/net/wireless/rtlwifi/rtl8192de/fw.c:236:2: warning: format ‘%lx’ expects
argument of type ‘long unsigned int’, but argument 5 has type ‘u32’ [-Wformat=]
  RT_TRACE(rtlpriv, COMP_FW, DBG_DMESG,
  ^

The format specifier should be %04x, not %08lx. I have no idea why gcc did not
complain as %08ul is also wrong.

Terribly sorry about that, and thanks for catching it. I naively assumed 
that the code was correct besides the decimal vs. hex issue.

Shouldn't it be %08x since it's a 32-bit value?

I assume the compiler would have warned about %08lu, but %08ul takes an 
unsigned and just prints an l afterwards.
