* nvme: use 64 bit types for timeouts even on 32 bit systemsAhmad Fatoum2019-08-301-2/+2
| | | | | | | | | The SHUTDOWN_TIMEOUT value of 5e9 would already exceed the range of unsigned long on a 32-bit system. Fix this by using uint64_t for all time-holding variables. Signed-off-by: Ahmad Fatoum <ahmad@a3f.at> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* treewide: replace '---help---' with 'help' in Kconfig filesMasahiro Yamada2019-05-171-1/+1
| | | | | | | | | | | | | | | | In Linux, '---help---' was deprecated in favor of 'help', and this is checked by the recent checkpatch.pl See Linux commit 84af7a6194e493fae312a2b7fa5a3b51f76d9282 The number of '---help---' is gradually decreasing in Linux, but there are still lots. However, '---help---' will be completely killed when the time comes. Fortunately, there are only some in Barebox. Replacing them is not hard.
