[PATCH 6.3 265/286] serial: cpm_uart: Fix a COMPILE_TEST dependency

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

 



From: Herve Codina <herve.codina@xxxxxxxxxxx>

commit 7183c37fd53eee1e795206e625da12a5d7ec1e1a upstream.

In a COMPILE_TEST configuration, the cpm_uart driver uses symbols from
the cpm_uart_cpm2.c file. This file is compiled only when CONFIG_CPM2 is
set.

Without this dependency, the linker fails with some missing symbols for
COMPILE_TEST configuration that needs SERIAL_CPM without enabling CPM2.

This lead to:
  depends on CPM2 || CPM1 || (PPC32 && CPM2 && COMPILE_TEST)

This dependency does not make sense anymore and can be simplified
removing all the COMPILE_TEST part.
