Don't allow sleep when getting the gpio value in the irq-handler.

struct timeval uses a 32-bit seconds representation which will overflow in the year 2038 and beyond. This patch replaces the usage of struct timeval with ktime_t which is a 64-bit timestamp and is year 2038 safe. This patch is part of a larger attempt to remove all instances of 32-bit timekeeping variables (timeval, timespec, time_t) which are not year 2038 safe, from the kernel.

Jemma Denson authored
The flexcop bridge chip has two banks of hardware pid filters - an initial 6, and on some chip revisions an additional bank of 32. A bug is present on the initial 6 - when changing transponders one of two PAT packets from the old transponder would be included in the initial packets from the new transponder. This usually transpired with userspace programs complaining about services missing, because they are seeing a PAT that they would not be expecting. Running in full TS mode does not exhibit this problem, neither does using just the additional 32. This patch adds in an option to not use the inital 6 and solely use just the additional 32, and enables this option for the SkystarS2 card. Other cards can be added as required if they also have this bug. Signed-off-by: Jemma Denson <jdenson@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

My static checker detected that free_irq() is called even after request_irq() failed in ddb_probe(). In this case, the kernel may try to free dev->pdev->irq although the IRQ is not assigned. This event rarely occurs, but always introduces a warning if it happens. "goto fail1" always results in disabling enabled MSI and releasing a requested IRQ. It seems like the former handling is necessary. So I added a conditional branch before the free_irq() (stat == 0 means request_irq() succeeds).

'struct timeval last_tv' is used to get the time of last signal change and 'struct timeval last_intr_tv' is used to get the time of last UART interrupt. 32-bit systems using 'struct timeval' will break in the year 2038, so we have to replace that code with more appropriate types. Here struct timeval is replaced with ktime_t.

The comment for struct dvb_frontend_parameters is weird, as it mixes delivery system name (ATSC) with modulation names (QPSK, QAM, OFDM). Use delivery system names there on the frequency comment, as this is clearer, specially after 2GEN delivery systems.

The DVB API was originally defined using typedefs. This is against Kernel CodingStyle, and there's no good usage here. While we can't remove its usage on userspace, we can avoid its usage in Kernelspace. So, let's do it. This patch was generated by this shell script: for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done While here, make CodingStyle fixes on the affected lines.
