Bruno Prémont 8c4e708d01 HID: picolcd: Avoid compile warning/error triggered by copy_from_user() 
With CONFIG_DEBUG_STRICT_USER_COPY_CHECKS=y compilation of PicoLCD
driver fails on copy_from_user(), without it a warning is generated:

In function 'copy_from_user',
    inlined from 'picolcd_debug_eeprom_write' at drivers/hid/hid-picolcd.c:1592:
arch/x86/include/asm/uaccess_32.h:212: error: call to 'copy_from_user_overflow' declared with attribute error: copy_from_user() buffer size is not provably correct

gcc-4.4.5 is not able to track size calculation when it is stored into
a variable, thus tell copy_from_user() maximum size via
min(*max-size*, *effective-size*) explicitly and inline how much to copy
at most.
