staging: kpc2000: report error status to spi core

2019-07-31T05:24:34+00:00

[ Upstream commit 9164f336311863d3e9f80840f4a1cce2aee293bd ] There is an error condition that's not reported to the spi core in kp_spi_transfer_one_message(). It should restore status value to m->status, and return it in error path. Signed-off-by: Mao Wenan Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin

staging: kpc2000: added missing clean-up to probe_core_uio.

2019-07-31T05:24:29+00:00

[ Upstream commit abb611d2c21c0a4fa8eab35dc936c80d9a07acd8 ] On error, probe_core_uio just returned an error without freeing resources which had previously been allocated. Added the missing clean-up code. Updated TODO. Signed-off-by: Jeremy Sowden Reviewed-by: Dan Carpenter Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin

staging: kpc2000: Add dependency on MFD_CORE to kconfig symbol 'KPC2000'

2019-05-24T07:41:09+00:00

The kpc2000 core makes calls against functions conditionally exported upon selection of the kconfig symbol MFD_CORE. Therefore, the kpc2000 core depends upon the mfd_core, and that dependency must be tracked in Kconfig to avoid potential build issues. Signed-off-by: Geordan Neukum Signed-off-by: Greg Kroah-Hartman

staging: kpc2000: double unlock in error handling in kpc_dma_transfer()

2019-05-20T07:18:45+00:00

The goto err_descr_too_many; calls unlock_engine() so this unlocks twice. Fixes: 7df95299b94a ("staging: kpc2000: Add DMA driver") Signed-off-by: Dan Carpenter Signed-off-by: Greg Kroah-Hartman

staging: kpc2000: fix build error on xtensa

2019-05-20T07:18:37+00:00

kpc2000/kpc_dma/fileops.c includes asm/uaccess.h instead of linux/uaccess.h, which results in the following build error on xtensa architecture: In file included from drivers/staging/kpc2000/kpc_dma/fileops.c:11: arch/xtensa/include/asm/uaccess.h: In function ‘clear_user’: arch/xtensa/include/asm/uaccess.h:40:22: error: implicit declaration of function ‘uaccess_kernel’; ... #define __kernel_ok (uaccess_kernel()) ^~~~~~~~~~~~~~ Include linux/uaccess.h to fix that.

Merge tag 'staging-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

2019-05-07T20:31:29+00:00

Pull staging / IIO driver updates from Greg KH: "Here is the big staging and iio driver update for 5.2-rc1. Lots of tiny fixes all over the staging and IIO driver trees here, along with some new IIO drivers. The "counter" subsystem was added in here as well, as it is needed by the IIO drivers and subsystem. Also we ended up deleting two drivers, making this pull request remove a few hundred thousand lines of code, always a nice thing to see. Both of the drivers removed have been replaced with "real" drivers in their various subsystem directories, and they will be coming to you from those locations during this merge window. There are some core vt/selection changes in here, that was due to some cleanups needed for the speakup fixes. Those have all been acked by the various subsystem maintainers (i.e. me), so those are ok. We also added a few new drivers, for some odd hardware, giving new developers plenty to work on with basic coding style cleanups to come in the near future. Other than that, nothing unusual here. All of these have been in linux-next for a while with no reported issues, other than an odd gcc warning for one of the new drivers that should be fixed up soon" [ I fixed up the warning myself - Linus ] * tag 'staging-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (663 commits) staging: kpc2000: kpc_spi: Fix build error for {read,write}q Staging: rtl8192e: Remove extra space before break statement Staging: rtl8192u: ieee80211: Fix if-else indentation warning Staging: rtl8192u: ieee80211: Fix indentation errors by removing extra spaces staging: most: cdev: fix chrdev_region leak in mod_exit staging: wlan-ng: Fix improper SPDX comment style staging: rtl8192u: ieee80211: Resolve ERROR reported by checkpatch staging: vc04_services: bcm2835-camera: Compress two lines into one line staging: rtl8723bs: core: Use !x in place of NULL comparison. staging: rtl8723bs: core: Prefer using the BIT Macro. staging: fieldbus: anybus-s: fix wait_for_completion_timeout return handling staging: kpc2000: fix up build problems with readq() staging: rtlwifi: move remaining phydm .h files staging: rtlwifi: strip down phydm .h files staging: rtlwifi: delete the staging driver staging: fieldbus: anybus-s: rename bus id field to avoid confusion staging: fieldbus: anybus-s: keep device bus id in bus endianness Staging: sm750fb: Change *array into *const array staging: rtl8192u: ieee80211: Fix spelling mistake staging: rtl8192u: ieee80211: Replace bit shifting with BIT macro ...

The 0-day system found a bunch of warnings for when readq() is not defined on the platform, so fix this by including the linux/io-64-nonatomic-lo-hi.h file which will fix up these issues. Reported-by: kbuild test robot Signed-off-by: Greg Kroah-Hartman

staging: kpc2000: fix resource size calculation

2019-04-30T12:19:04+00:00

The code is calculating the resource size wrong because it should be inclusive of the "res->end" address. In other words, "end - start + 1". We can just use the resource_size() function to do it correctly.
