ata: pata_cs5535: Fix W=1 warnings
x86_64 allmodconfig build with W=1 gives these warnings: drivers/ata/pata_cs5535.c: In function ‘cs5535_set_piomode’: drivers/ata/pata_cs5535.c:93:11: error: variable ‘dummy’ set but not used [-Werror=unused-but-set-variable] u32 reg, dummy; ^~~~~ drivers/ata/pata_cs5535.c: In function ‘cs5535_set_dmamode’: drivers/ata/pata_cs5535.c:132:11: error: variable ‘dummy’ set but not used [-Werror=unused-but-set-variable] u32 reg, dummy; ^~~~~ cc1: all warnings being treated as errors Mark variables 'dummy' as "maybe unused" as they are only ever written in rdmsr() calls.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
