Subject: [PATCH 0/5] usb-misc: cleanup sisusbvga

The file

drivers/usb/misc/sisusbvga/sisusb.c

had many (192) coding style issues reported by checkpatch. This file also had a
problematic error path in the probe function that could result in dereferencing
a null pointer.

This patch series fix coding style issues and fix the problematic error path to
avoid the null pointer dereference.

Patch 1 is the biggest and fix only whitespace, tab and newline issues. I used

$ git diff -w --word-diff=porcelain drivers/usb/misc/sisusbvga/sisusb.c

to verify that this patch do not change any visible character. If the size of
this patch is a problem, please let me know in how many patches to split it.

Patch 2 follows fixing trivial coding style, mostly related to braces,
and parenthesis.

Patch 3 remove assignments from if tests.

Patch 4 remove calls to dev_err() on memory allocation failures and fix one
error path to avoid dereferencing a null pointer. The patch change the
problematic error path to cleanup previously allocated resources and abort the
probe with -ENOMEM instead of only calling dev_err() and continue with the
probe.

Patch 5 remove null tests before calls to kfree().
