[PATCH] staging: greybus: power_supply: fix prop-descriptor request size

by Johan Hovold

Since moving the message buffers off the stack, the dynamically allocated get-prop-descriptor request buffer is incorrectly sized due to using the pointer rather than request-struct size when creating the operation. Fortunately, the pointer size is always larger than this one-byte request, but this could still cause trouble on the remote end due to the unexpected message size.

Greetings to you my dear. It’s my pleasure to contact you through this media. Excuse my interruption into your private life without your prior permission. I hope my mail will not cause you much embarrassment as I write to you in good faith. I know this message might come to you as a surprise because you don’t know me in person but it is only God that brought us together. My names are is Ms. Djamila Salif I am the regional chief account manager of one of the Prime Bank herein Burkina Faso. I am 31 years old lady, single. I am a young woman of peace and I don't want problems in my life. I have packaged a financial transaction that will benefit both of us. As the regional account manager of the Ecobank Plc Burkina Faso branch. It is my duty to send in a financial report of my customers to our head office in the capital at the end of each year. But in the course of the last year 2018 fiscal report, I discovered that one of my foreign customer late (Hon. Mr. Ghazi al-Sadiq Abdel Rahim) who died during the Sudan crash on 9 August 2012, you can read more about the crash through this site: https://www.bbc.co.uk/news/world-africa-19310609 My head office are not aware of it and it will never be aware of this transaction. He was a business magnate & Sudanese government's religion minister. He deposited the sum of $18.500, 000.00. This fund have been placed in what we call "escrow call" account with no beneficiary. As an officer of this bank I cannot be directly connected to this money, so my aim of contacting you is for you to assist me to receive this money in your country through your bank account, and get 50% of the total funds as commission/share while 50% for me. Since you are from another country outside Burkina Faso, I need your cooperation to stand as the next of kin to the defunct customer of our bank who died in the crash. I have made every attempt to searching for his blood relation or any family member who can stand to inherit the money without any fruitful result. To be very honest with you, this money I have opened-up to you is totally genuine no complications and is 100% risk-free. I am absolutely assuring you that no problem involved in this fund either in the short-run or in the long-run of this transaction. I have every information about this money and I will be backing you up with information that can make you claim the money from our bank but you will not tell anybody in my bank that the information is from my side. By virtue of my position, I can guarantee you that we stand a great chance of success in this transaction, If you are interested, please indicate your willingness to initiate the process by contacting me via email to enable us discuss the terms and conditions under which this transaction would be carried out. (1) Please my dear do you also have any business Idea where we can invest the fund? (2) Do we invest the fund in your company or in your business? (3) Or Maybe we should register a new company? Reply me If only you are interested in this deal, I will give you further details of the transaction Yours Sincerely Ms.Djamila Salif, Regional account manager Ecobank Plc Burkina Faso.

[PATCH v7 0/3] greybus: gpio: Switch to the gpio descriptor interface

by Nishad Kamdar

This patch series converts uses of the old GPIO API to the GPIO descriptor API. It also converts the GPIO driver to use the GPIO irqchip library GPIOLIB_IRQCHIP instead of repimplementing the same. Chnages in v7: - Combine the three patches together. Changes in v6: - Patchset now contains two patches as the patch 1 has been accepted. - Changes mentioned in individual patches of the set. Changes in v5: - Drop the patch which uses gpiochip_get_data() in place of gpio_chip_to_gb_gpio_controller() as of now. - This is because it currently breaks the driver, since gpiochip_add() sets the data pointer to NULL. Changes in v4: - Changes mentioned in individual patches of the set. Changes in v3: - Combines the latest versions of the three greybus patches together in a patch series.
