Subject: [PATCH 07/11] mtd: rawnand: denali: use bool type instead of int where appropriate
Date: Fri,  8 Feb 2019 17:08:51 +0900	[thread overview]
Message-ID: <1549613335-30319-8-git-send-email-yamada.masahiro@socionext.com> (raw)
In-Reply-To: <1549613335-30319-1-git-send-email-yamada.masahiro@socionext.com>

Use 'bool' type for some function arguments.

 - write (write or read?)
 - raw (the raw access mode or not?)

It is true that denali_nand_info::dma_avail is also boolean, but
I am keeping it as 'int' because 'scripts/checkpatch --strict' would
report the following:

CHECK: Avoid using bool structure members because of possible alignment issues
  - see: https://lkml.org/lkml/2017/11/21/384

I do not think it is a matter here, but I am sticking to the suggestion.
