serial: fix missing bit coverage of ASYNC_FLAGS
It seems that currently ASYNC_FLAGS is one bit short of covering all the bits of the ASYNC user flags. In particular it does not cover the ASYNC_AUTOPROBE bit. ASYNCB_LAST_USER and ASYNCB_AUTOPROBE are both equal to 15. Therefore: ASYNC_AUTOPROBE = 1000 0000 0000 0000 ASYNC_FLAGS = 0111 1111 1111 1111 So ASYNC_FLAGS is not covering the ASYNC_AUTOPROBE bit. This patch fixes the issue and with the patch the values will be: ASYNC_AUTOPROBE = 1000 0000 0000 0000 ASYNC_FLAGS = 1111 1111 1111 1111 As a side note, doing a "git grep" I didn't find any use of ASYNC_AUTOPROBE or ASYNCB_AUTOPROBE in the kernel, besides this include file.
