Revert "of: base: Introduce of_alias_get_alias_list() to check alias IDs"
This reverts commit b1078c355d76769b5ddefc67d143fbd9b6e52c05. The single user of of_alias_get_alias_list(), drivers/tty/serial/xilinx_uartps.c, has since been refactored and no longer needs this function. It also contained a Smatch checker warning: drivers/of/base.c:2038 of_alias_get_alias_list() warn: passing negative bit value 's32min-(-2),0-s32max' to 'set_bit()' Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Rob Herring <robh@kernel.org>
