Despite never getting called from atomic context, usb URB memory allocations use GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it. [mchehab+samsung@kernel.org: merged 3 similar patches into one] Signed-off-by:

The tuner is used in Earthsoft PT1/PT2 DVB boards, and the driver was extraced from (the former) va1j5jf8007s.c of PT1. it might contain PT1 specific configs. Signed-off-by:

This patch adds a PLL "description" of Philips TDA6651 for ISDB-T. It was extracted from (the former) va1j5jf8007t.c of EarthSoft PT1, thus the desc might include PT1 specific configs. Signed-off-by:

As the kernel doc "timers-howto.txt" reads, short delay with msleep() can take much longer. In a case of raspbery-pi platform where CONFIG_HZ_100 was set, it actually affected the init of Friio devices since it issues lots of i2c transactions with short delay. Signed-off-by:

Three really tiny minors in this single commit which all on their own would just clutter up the commit history unnecessarily: * ddbridge-regs.h is lacking an include guard. Add it. * Fix an unnecessary NULL initialisation in ddbridge-ci. The declaration of the ci struct ptr is immediately followed by kzalloc(). * Clarify that the CXD2099AR is a Sony device in the cxd2099 driver at a few places including Kconfig. Signed-off-by:

The -Warray-bounds warning in gcc-8 triggers for a newly added file: drivers/media/spi/cxd2880-spi.c: In function 'cxd2880_write_reg': drivers/media/spi/cxd2880-spi.c:111:3: error: 'memcpy' forming offset [133, 258] is out of the bounds [0, 132] of object 'send_data' with type 'u8[132]' {aka 'unsigned char[132]'} [-Werror=array-bounds] The problem appears to be that we have two range checks in this function, first comparing against BURST_WRITE_MAX (128) and then comparing against a literal '255'. The logic checking the buffer size looks at the second one and decides that this might be the actual maximum data length. This is understandable behavior from the compiler, but the code is actually safe. Since the first check is already shorter, we can remove the loop and only leave that. To be on the safe side in case BURST_WRITE_MAX might be increased, I'm leaving the check against U8_MAX.

Show the UCB error counts via DVBv5. Please notice that there's no scale indication at the driver. As we don't have the datasheet, let's assume that it is receiving data at a rate of 10.000 packets per second. Ideally, this should be read or estimated. In order to avoid flooding I2C bus with data, the maximum polling rate for those stats was set to 1 second. Signed-off-by:
