[PATCH v2] usb: ucsi: stm32: fix command completion handling

by Fabrice Gasnier

Sometimes errors are seen, when doing DR swap, like: [ 24.672481] ucsi-stm32g0-i2c 0-0035: UCSI_GET_PDOS failed (-5) [ 24.720188] ucsi-stm32g0-i2c 0-0035: ucsi_handle_connector_change: GET_CONNECTOR_STATUS failed (-5) There may be some race, which lead to read CCI, before the command complete flag is set, hence returning -EIO. Similar fix has been done also in ucsi_acpi [1]. In case of a spurious or otherwise delayed notification it is possible that CCI still reports the previous completion. The UCSI spec is aware of this and provides two completion bits in CCI, one for normal commands and one for acks. As acks and commands alternate the notification handler can determine if the completion bit is from the current command. To fix this add the ACK_PENDING bit for ucsi_stm32g0 and only complete commands if the completion bit matches.

[tip: x86/urgent] x86/boot: Don't add the EFI stub to targets, again

by tip-bot2 for Benjamin Segall

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: b2747f108b8034271fd5289bd8f3a7003e0775a3 Gitweb: https://git.kernel.org/tip/b2747f108b8034271fd5289bd8f3a7003e0775a3 Author: Benjamin Segall <bsegall(a)google.com> AuthorDate: Wed, 12 Jun 2024 12:44:44 -07:00 Committer: Borislav Petkov (AMD) <bp(a)alien8.de> CommitterDate: Thu, 13 Jun 2024 10:32:36 +02:00 x86/boot: Don't add the EFI stub to targets, again This is a re-commit of da05b143a308 ("x86/boot: Don't add the EFI stub to targets") after the tagged patch incorrectly reverted it. vmlinux-objs-y is added to targets, with an assumption that they are all relative to $(obj); adding a $(objtree)/drivers/... path causes the build to incorrectly create a useless arch/x86/boot/compressed/drivers/... directory tree. Fix this just by using a different make variable for the EFI stub.
