net: wireless: rt2x00: fix CRC_CCITT dependency

[PATCH] net: wireless: rt2x00: fix CRC_CCITT dependency

Posted by Arnd Bergmann 6 months, 1 week ago

From: Arnd Bergmann <arnd@arndb.de>

Compile-testing this driver on Arm platforms shows a link failure
when the CRC functions are not part of the kernel:

x86_64-linux-ld: drivers/net/wireless/ralink/rt2x00/rt2800lib.o: in function `rt2800_check_firmware':
rt2800lib.c:(.text+0x20e5): undefined reference to `crc_ccitt'

Move the select statement to the correct Kconfig symbol to match
the call site.

Fixes: 311b05e235cf ("wifi: rt2x00: add COMPILE_TEST")
