[PATCH 2/2] serial: pch_uart: Fix build warning when CONFIG_DEBUG_FS=n

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

 



Add CONFIG_DEBUG_FS to 'char name' in order to fix the following
build warning, because 'char name' is used only when CONFIG_DEBUG_FS
is enabled.

drivers/tty/serial/pch_uart.c:1765:7: warning: unused variable 'name' [-Wunused-variable]
