Subject: clang: net: qed_main.c:1227:3: error: 'snprintf' will always be
 truncated; specified size is 16, but format string expands to at least 18 [-Werror,-Wfortify-source]

[My two cents]

stable-rc linux-6.1.y and linux-6.4.y x86 clang-nightly builds fail with
following warnings / errors.

Build errors:
--------------
drivers/net/ethernet/qlogic/qed/qed_main.c:1227:3: error: 'snprintf'
will always be truncated; specified size is 16, but format string
expands to at least 18 [-Werror,-Wfortify-source]
