[PATCH] drm/dp_mst: Fix build on systems with STACKTRACE_SUPPORT=n

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On systems with STACKTRACE_SUPPORT=n, we get:

WARNING: unmet direct dependencies detected for STACKTRACE
  Depends on [n]: STACKTRACE_SUPPORT
  Selected by [y]:
  - STACKDEPOT [=y]

and build errors such as:

m68k-linux-ld: kernel/stacktrace.o: in function `stack_trace_save':
(.text+0x11c): undefined reference to `save_stack_trace'

Add the missing deendency on STACKTRACE_SUPPORT.

Fixes: 12a280c72868 ("drm/dp_mst: Add topology ref history tracking for debugging")
