This was due to a wrong vendor blob . deleting that from vendor folder solved it .

it was my mistake ,
initially when i run the

mka mkbootimg

I got this error

error: vendor/xiaomi/whyred: MODULE.TARGET.SHARED_LIBRARIES.libsdm-disp-vndapis already defined by vendor/xiaomi/whyred.

To resolve this I commented out those modules from vendor/xiaomi/whyred/Android.mk .

I accidentally commented out libantradio module too .

undoing that resolved the issue .
