[PATCH v2] staging: vboxvideo: Remove unnecessary parentheses

[Shayenne da Luz Moura]

clutter and code behave in the same way.
Change suggested by checkpatch.pl.

crtc->x'

This patch does not apply to the latest kernel tree at all :(

Please fix up and resend.

Hi Greg!

Sorry, I do not know what branch are expected to be used.
I used the drm-misc-next to create this patch and I could not
find any merge problem.

Could you please tell me the details?

Thanks,

Shayenne

Hi Shayenne,

There's an easy trick for this: the kernel tree has a script that can
help you find both the relevant maintainers, and their development tree
for each file in the kernel.

Simply run:

	./scripts/get_maintainer.pl --scm -f [filename]

For example, in this case, you'd run:

	$ ./scripts/get_maintainer.pl --scm -f drivers/staging/vboxvideo/vbox_main.c
	Greg Kroah-Hartman <gregkh@linuxfoundation.org> (supporter:STAGING SUBSYSTEM,commit_signer:10/10=100%)
	Hans de Goede <hdegoede@redhat.com> (commit_signer:7/10=70%,authored:6/10=60%,added_lines:31/37=84%,removed_lines:153/159=96%)
	Fabio Rafael da Rosa <fdr@pid42.net> (commit_signer:1/10=10%,authored:1/10=10%)
	Alexander Kapshuk <alexander.kapshuk@gmail.com> (commit_signer:1/10=10%,authored:1/10=10%)
	Nicholas Mc Guire <der.herr@hofr.at> (commit_signer:1/10=10%)
	Thomas Zimmermann <tzimmermann@suse.de> (authored:1/10=10%,added_lines:2/37=5%)
	Daniel Junho <djunho@gmail.com> (authored:1/10=10%,added_lines:2/37=5%)
	devel@driverdev.osuosl.org (open list:STAGING SUBSYSTEM)
	linux-kernel@vger.kernel.org (open list)
	git git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git

The list of people and mailing lists are the ones that should be the
recipients of your patch, and the last line is the git tree on which the
patch should be based on.

For staging drivers you should use the staging tree as indicated in the
outreachy tutorial.
