That meant that spi devices on that bus would be\nunable to do IO in their remove method.  The shutdown flag should have been\nable to prevent a segfault, but was never getting set.  By waiting to\ndestroy the workqueue until after the master is unregistered, devices are\nable to do IO in their remove methods.

      "message": "[PATCH] SPI: define null tx_buf to mean \"shift out zeroes\"\n\nSome issues were recently turned up with the current specification of what\nit means for spi_transfer.tx_buf to be null, as part of transfers which are\n(from the SPI protocol driver perspective) pure reads.\n\nSpecifically, that it seems better to change the TX behaviour there from\n\"undefined\" to \"will shift zeroes\".  This lets protocol drivers (like the\nads7846 driver) depend on that behavior.  It\u0027s what most controller drivers\nin the tree are already doing (with one exception and one case of driver\nwanting-to-oops), it\u0027s what Microwire hardware will necessarily be doing,\nand it removes an issue whereby certain security audits would need to\ndefine such a value anyway as part of removing covert channels.\n\nThis patch changes the specification to require shifting zeroes, and\nupdates all currently merged SPI controller drivers to do so.\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nSigned-off-by: Kumar Gala \u003cgalak@kernel.crashing.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
