The function dump_chip_info() is only used in rtl8188e_hal_init.c.
Make it static to reduce the driver object file size by 281 bytes.
before:
text data bss dec hex filename

Probably better and likely smaller without the temporary buffer
and the possibility of overrun.
Something like:
{
char cut[25];
char *v = NULL;
switch (chip_vers.CUTVersion) {
case A_CUT_VERSION:
v = "A_CUT";
break;
case B_CUT_VERSION:
v = "B_CUT";
break;
case C_CUT_VERSION:
v = "C_CUT";
break;
case D_CUT_VERSION:
v = "D_CUT";
break;
case E_CUT_VERSION:
v = "E_CUT";
break;
default:
snprintf(cut, sizeof(cut), "UNKNOWN_CUT(%d)", chip_vers.CUTVersion);
v = cut;
break;
}
pr_info("Chip Version Info: CHIP_8188E_%s__Chip_%s_%s_1T1R_RomVer(%d)\n",
IS_NORMAL_CHIP(chip_vers) ? "Normal" : "Test",
IS_CHIP_VENDOR_TSMC(chip_vers) ? "TSMC" : "UMC",
v, 0);
}

Nit, none of this should be sent to the kernel log if all is good. When
drivers are working properly, they are quiet. This is spamming the
kernel log for when things are working properly, which just slows
booting down.
Also no driver should be calling pr_*() calls when they have a real
device at hand.
So this should be moved to be a dev_dbg() so that developers can still
enable it when they want to see this information, but it doesn't spam
the log for normal users. But that's all for a future change, this one
is fine as-is, I'll take it now, thanks.
