5.4.102 backported a lot of stuff that our WireGuard backport already did, in addition to other patches we had, so those patches were removed from that part of the series. In the process other patches were refreshed or reworked to account for upstream changes. This commit involved `update_kernel.sh -v -u 5.4`.

Subject: [PATCH] mtd: spi-nor: allow NOR driver to write fewer bytes than
|
|
requested
|
|
|
|
The write size can be constrained by the maximum message/transfer size
|
|
of the SPI controller. Only check for ret = 0 to avoid an infinite loop.
