get_req_from_tcs introduced in patch[1] returns tcs_request from
tcs_group. The size of tcs (of type - tcs_group) array in rsc_drv is
TCS_TYPE_NR. So the loop index needs to be iterated up to TCS_TYPE_NR only.

function as well.

Add the ISO7816 ioctl and associated accessors and data structure.
Drivers can then use this common implementation to handle ISO7816.

Hi,
This patchset adds support for the ISO7816 standard. The USART devices in
Microchip SoCs have an ISO7816 mode. It allows to let the USART managing
the CLK and I/O signals of a smart card.
Changes:
- v2
- uart_get_iso7816_config: check there is an iso7816_config function
- use IOCTL macros
It seems contributors follow the style of Kconfig entries where explicit
'default n' is present. The default 'default' is 'n' already, thus, drop
these lines from Kconfig to make it more clear.

I was thinking about this too.
