[BUG] stat() does not work on flash partition with BCH layer #16074
Description
Description / Steps to reproduce the issue
Flash partition configured as BCH layer (device driver created with bchdev_register) doesn't allow stat call to obtain the information about an underlying MTD device/flash. This is caused by INODE_IS_MTD not being set and thus
function inode_stat falls to the last else statement and does not fill the necessary information.
This is a logical output as BCH layer is registered as a standard character device driver, therefore it is not considered as MTD but as a standard driver (ADC, PWM, etc.). This, however, makes the stat call unusable for it.
We should probably find a way how to pass an information there is a MTD device under the driver and that we should access it with a standard MTDIOC_GEOMETRY ioctl to obtain the required information and pass them to the user.
