Subject: [PATCH] mtd: spi-nor: Simplify loop in spi_nor_read_id()
Date: Tue, 18 Feb 2020 16:10:34 +0100 [thread overview]
Message-ID: <20200218151034.24744-1-j.neuschaefer@gmx.net> (raw)
- Don't use `tmp` for two purposes (return value, loop counter)
- Name the loop counter `i`, as is convention
- Return the pointer variable that the if conditions leading up to the
return statement already operate on, rather than a different
expression that evaluates to the same pointer
