[PATCH] Bluetooth: btmtk: Fix btmtk.c undefined reference build error

[Chris Lu]

MediaTek move some usb interface related function to btmtk.c which
may cause build failed if BT USB Kconfig wasn't enabled.
Fix undefined reference by adding config check.

Fixes: 39a9e1c69e74 Bluetooth: btmtk: move btusb_mtk_hci_wmt_sync to btmtk.c

If I recall this correctly it is not a good practice to use #if inside
structs as it would change its overall size, memory layout, etc, and
it also makes it difficult to use if (IS_DEFINED) and let the compiler
eliminate dead code instead of using the preprocessor like you doing.

"#if" can be remove here, usb.h was included in each c file in case 
making certain compiler error as you mentioned. It should be fine not
to separate these element. I'm able to build pass after remove the
"#if" here locally with same Kconfig.

I saw someone sent another patch for this issue by adding inline  to
each function. It would be another way to avoid undefined reference.
