* [media] si2165: switch to regmapMatthias Schwarzott2016-09-22
| | | | | | | | | This avoids some low-level operations. It has the benefit that now register values van be read from /sys/kernel/debug/regmap The maximum register value is just a guess - all higher addresses read as zero.

* [media] si2165: use i2c_client->dev instead of i2c_adapter->dev for loggingMatthias Schwarzott2016-09-22

* [media] si2165: avoid division by zeroMatthias Schwarzott2016-09-22
| | | | | | | | | | | | | | | | | When si2165_init fails, the clk values in state are still at zero. But the dvb-core ignores the return value of init will call tune afterwards. This will trigger a division by zero when tuning. At least check for the variables to be non-zero before dividing. This happened for a system with WinTV HVR-4400 PCIe-card after suspend-to-disk. Do suspend-to-disk without accessing the DVB device before. After wakeup try to tune. si2165_init fails at checking the chip_mode and aborts. Then si2165_set_if_freq_shift will fail with div-by-zero.

* [media] si2165: Refactoring for si2165_writereg_mask8()Markus Elfring2016-01-25
| | | | | | | | | | | | | | | | | | | This issue was detected by using the Coccinelle software. 1. Let us return directly if a call of the si2165_readreg8() function failed. 2. Reduce the scope for the local variables "ret" and "tmp" to one branch of an if statement. 3. Delete the jump label "err" then. 4. Return the value from a call of the si2165_writereg8() function without using an extra assignment for the variable "ret" at the end.

* [media] dvb: Get rid of typedev usage for enumsMauro Carvalho Chehab2015-06-09
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | In case of an error function si2165_upload_firmware() releases the already requested firmware in the exit path.
