I think the following code would be better:

cfg.phys_addr -= cfg.phys_addr % INTERNAL_FLASH_SECTOR_SIZE;


maxAllowedSector = flashmem_get_sector_of_address(INTERNAL_FLASH_SIZE - 1);
requestedSector = flashmem_get_sector_of_address((cfg.phys_addr + SPIFF_SIZE) - 1);
if(requestedSector > maxAllowedSector) {
debug_w("The requested SPIFFS size is too big.");
cfg.phys_size = (maxAllowedEndAddress + 1) - ( ( u32_t )cfg.phys_addr);
}
else {
cfg.phys_size = SPIFF_SIZE;
requestedSector = maxAllowedSector;
}
cfg.phys_size = ((requestedSector + 1) * INTERNAL_FLASH_SECTOR_SIZE) - ( ( u32_t )cfg.phys_addr); // get the max size until the sector end.

cfg.phys_erase_block = INTERNAL_FLASH_SECTOR_SIZE; // according to datasheet
cfg.log_block_size = INTERNAL_FLASH_SECTOR_SIZE * 2; // Important to make large
