b95d0899 - usb: use "prompt" instead of "bool" for choice prompts

Sun, 29 Sep 2024 17:32:36 +0000

usb: use "prompt" instead of "bool" for choice promptsSince commit fde192511bdb ("kconfig: remove tristate choice support"),all choice blocks are now boolean. There is no longer a need to specifythe choice type explicitly.Most choice blocks already use "prompt". Before the next commit removessupport for the "bool" syntax in choice entries, this commit convertsthe remaining "bool" occurences under drivers/usb/.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/drivers/usb/dwc2/Kconfig

d991f855 - usb: remove redundant 'default n' from Kconfig-s

Mon, 20 May 2019 14:14:33 +0000

usb: remove redundant 'default n' from Kconfig-s'default n' is the default value for any bool or tristate Kconfigsetting so there is no need to write it explicitly.Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOOis not set' for visible symbols") the Kconfig behavior is the sameregardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/dwc2/Kconfig

This allows it toaccount for changes to the platform driver that were not added to thepci driver. Also future changes to the probe function don't have to beduplicated. This also has the effect of adding device and DRD mode tothe pci driver.
