2018-07-11staging: vt6655: remove some redundant variablesColin Ian King
Variables rx_sts, sq, frame and is_pspoll are being assigned but are never used hence they are redundant and can be removed. Cleans up clang warnings: warning: variable 'sq' set but not used [-Wunused-but-set-variable] warning: variable 'rx_sts' set but not used [-Wunused-but-set-variable] warning: variable 'frame' set but not used [-Wunused-but-set-variable] warning: variable 'is_pspoll' set but not used [-Wunused-but-set-variable] Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-11-28staging: vt6655: Remove redundant license textGreg Kroah-Hartman
Now that the SPDX tag is in all vt6655 files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

2017-11-28staging: vt6655: add SPDX identifiers to all vt6655 driver filesGreg Kroah-Hartman
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the vt6655 driver files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2016-10-16staging: vt6655: Removes the FSF mailing address.Varsha Rao
This patch fixes the checkpatch issue by removing the Free Software Foundation's mailing address from the sample GPL notice. Because the FSF has changed address in the past, and may change again.
