[PATCH v2 07/13] tty: Convert ->dtr_rts() to take bool argument

by Ilpo Järvinen

Convert the raise/on parameter in ->dtr_rts() to bool through the callchain. The parameter is used like bool. In USB serial, there remains a few implicit bool -> larger type conversions because some devices use u8 in their control messages. In moxa_tiocmget(), dtr variable was reused for line status which requires int so use a separate variable for status.

[PATCH 07/10] tty: Convert ->dtr_rts() to take bool argument

by Ilpo Järvinen

Convert the raise/on parameter in ->dtr_rts() to bool through the callchain. The parameter is used like bool. In USB serial, there remains a few implicit bool -> larger type conversions because some devices use u8 in their control messages.

[PATCH v2] staging: greybus: Replace zero-length array by DECLARE_FLEX_ARRAY() helper

by Deepak R Varma

The code currently uses C90 standard extension based zero length array struct which is now deprecated and the new C99 standard extension of flexible array declarations are to be used instead. Also, the macro DECLARE_FLEX_ARRAY() allows to use single flexible array member in a structure. Refer to these links [1], [2], and [3] for details.

[PATCH 11/30] greybus: svc: Use kstrtobool() instead of strtobool()

by Christophe JAILLET

strtobool() is the same as kstrtobool(). However, the latter is more used within the kernel. In order to remove strtobool() and slightly simplify kstrtox.h, switch to the other function name. While at it, include the corresponding header file (<linux/kstrtox.h>) Signed-off-by: Christophe JAILLET <christophe.jaillet(a)wanadoo.fr> --- This patch is part of a serie that axes all usages of strtobool(). Each patch can be applied independently from the other ones. The last patch of the serie removes the definition of strtobool(). You may not be in copy of the cover letter. So, if needed, it is available at [1].
