Compiler warnings in flash.h: invalid conversion from 'const void*' to 'const flash_driver_api*'

[szundi]

There is a missing cast in /include/drivers/flash.h, i checked it on master too.

These are only warnings:
In file included from ../src/main.cpp:15: /Users/szundi/zephyrproject/zephyr/include/drivers/flash.h: In function 'int z_impl_flash_read(device*, off_t, void*, size_t)': /Users/szundi/zephyrproject/zephyr/include/drivers/flash.h:104:44: warning: invalid conversion from 'const void*' to 'const flash_driver_api*' [-fpermissive] 104 | const struct flash_driver_api *api = dev->driver_api; | ~~~~~^~~~~~~~~~ | | | const void* /Users/szundi/zephyrproject/zephyr/include/drivers/flash.h: In function 'int z_impl_flash_write(device*, off_t, const void*, size_t)': /Users/szundi/zephyrproject/zephyr/include/drivers/flash.h:128:44: warning: invalid conversion from 'const void*' to 'const flash_driver_api*' [-fpermissive] 128 | const struct flash_driver_api *api = dev->driver_api; | ~~~~~^~~~~~~~~~ | | | const void* /Users/szundi/zephyrproject/zephyr/include/drivers/flash.h: In function 'int z_impl_flash_erase(device*, off_t, size_t)': /Users/szundi/zephyrproject/zephyr/include/drivers/flash.h:159:44: warning: invalid conversion from 'const void*' to 'const flash_driver_api*' [-fpermissive] 159 | const struct flash_driver_api *api = dev->driver_api; | ~~~~~^~~~~~~~~~ | | | const void* /Users/szundi/zephyrproject/zephyr/include/drivers/flash.h: In function 'int z_impl_flash_write_protection_set(device*, bool)': /Users/szundi/zephyrproject/zephyr/include/drivers/flash.h:185:44: warning: invalid conversion from 'const void*' to 'const flash_driver_api*' [-fpermissive] 185 | const struct flash_driver_api *api = dev->driver_api; | ~~~~~^~~~~~~~~~ | | | const void* /Users/szundi/zephyrproject/zephyr/include/drivers/flash.h: In function 'size_t z_impl_flash_get_write_block_size(device*)': /Users/szundi/zephyrproject/zephyr/include/drivers/flash.h:272:44: warning: invalid conversion from 'const void*' to 'const flash_driver_api*' [-fpermissive] 272 | const struct flash_driver_api *api = dev->driver_api; | ~~~~~^~~~~~~~~~ | | | const void*
