dvb_frontend will call dvb_detach for: - stb0899_detach in dvb_frontend_release and - stb0899_release in __dvb_frontend_free But we only do dvb_attach(stb0899_attach). Increment the module refcount instead. Signed-off-by:

drivers/media/dvb-core/dvb_frontend.c:154:2-7: WARNING: NULL check before freeing functions like kfree, debugfs_remove, debugfs_remove_recursive or usb_free_urb is not needed. Maybe consider reorganizing relevant code to avoid passing NULL values. NULL check before some freeing functions is not needed. Based on checkpatch warning "kfree(NULL) is safe this check is probably not required" and kfreeaddr.cocci by Julia Lawall.

The result (if any) isn't used anywhere besides being assigned to a local variable (and the only current companion stv6111 doesn't even implement get_if_frequency()), thus remove the ptr check and the call, and also remove the now unused iffreq variable. Reported-by:

When a parent (demod) driver encounters and signals a problem with gate_ctrl(), don't blindly continue poking the I2C bus. Signed-off-by:

Daniel Scheller authored
Stack dump when gate_ctrl() is called in a way that consecutive unlocks happen. This is a clear indication that other drivers interfacing with the stv0910 driver don't do things properly or don't check for failures, so dump stack so that those drivers can be identified and fixed. Signed-off-by:

Each field (FSTV0910_XX) is declared as reg/off/unused/sign/mask. Add the missing offset value to the defines. Picked up from dddvb master, commit 8a1f27c3d22c ("add field offset to field defines") by Ralph Metzler <rjkm@metzlerbros.de>, adapted to match the comment style in the mainline driver.

_channel_ is being dereferenced before it is null checked, hence there is a potential null pointer dereference. Fix this by moving the pointer dereference after _channel_ has been null checked.
